Full gallery of pictures can be downloaded on my other blog Car wallpapers.


The Mazda booth at the Jacob Javits Convention Center will be a very popular destination during this year’s auto show. Mazda will show off its newest concept car, the Mazda Furai, and the freshened 2009 Mazda RX-8 sports car at the 2008 New York International Auto Show (NYIAS), to be held in New York from Wednesday, March 19 through Sunday, March 30, 2008.MAZDA FURAI –‘SOUND OF WIND’ Inspired by the fact that, on any given weekend, there are more Mazdas and Mazda-powered cars road-raced in the United States than any other brand, the Mazda Furai (Japanese for “sound of the wind” and pronounced “foo-rye”) is the sort of car that could only come from a company that incorporates the “Soul of a Sports Car” into everything it builds, but with an eye toward the future and the environment. Furai was tuned to run on 100% ethanol, and the company’s partnership with BP will see future and renewable fuels jointly developed. Furai takes Mazda’s unique Nagare (Japanese for “flow”) design language a step further as it is translated into a concept car based on an American Le Mans Series (ALMS) racing car. The car utilizes the Courage C65 chassis the company campaigned in the ALMS series only two seasons ago, and the 450-hp three-rotor rotary engine that distinguishes it from anything else on the track. Says Franz von Holzhausen, Mazda’s North American director of design, “Furai purposely blurs boundaries that have traditionally distinguished street cars from track cars. Historically, there has been a gap between single-purpose racecars and street-legal models — commonly called supercars — that emulate the real racers on the road. Furai bridges that gap like no car has ever done before.” Mazda’s critically acclaimed Nagare design language describes the flow of water, air, people or things moving in one direction. Mazda Nagare is flow, with an insightful and spirited styling, which, in Mazda Furai, invokes a raw, unfettered desire to possess everything this car represents.2009 MAZDA RX-8 The 2009 Mazda RX-8 continues to be a “Sports Car like no other,” and shows that the rotary engine is still an important part of Mazda’s future. For 2009, Mazda will further the evolution of the four-door, four-seater sports coupe, giving RX-8 a refreshed exterior and interior design, enhanced performance and a new R3 sport package for the ultimate driving enthusiast. Unchanged is the core of the RX-8 – a high-powered, lightweight and perfectly balanced machine powered by the world-renowned twin-rotor RENESIS rotary engine. Since its launch in 2003, the Mazda RX-8 has been hailed as a genuine sports car, but with a totally new, four-door, four-seat format that delivers sports car values, passenger comfort and driving pleasure. Powered by the world’s only mass-produced rotary engine, RX-8 is the spiritual successor to the 1967 Cosmo 110S, the world’s first twin-rotor production car. With almost two-million rotary engines sold, and the company’s legendary win at the 1991 24 Hours of Le Mans – the only Japanese brand to ever win the endurance racing classic – the rotary engine is the sole preserve of Mazda.CX-9 AND THE FULL MAZDA LINEUP In addition to Furai and the 2009 RX-8, Mazda will display the full 2008 lineup of cars and SUVs. Of particular interest will be the Mazda CX-9, one of the most award-winning and successful vehicles in Mazda’s history. CX-9 was recently named the 2008 North American Truck of the Year award, along with the 2008 Motor Trend Sport/Utility of the Year. Media is not alone in recognizing the vehicle. Launched in 2007, the award-winning CX-9 recorded sales of 25,566 in just ten months. Combined with the awards and attention it has garnered, the CX-9 proves that it is truly best in class.

Mercedes-Benz SL63 AMG Roadster

MONTVALE, NJ – Mercedes-Benz is unveiling a fourth member of its iconic SL sports car

family – the SL63 AMG. Perhaps the sportiest SL roadster ever, the new SL63 AMG is powered by a 6.2-liter, 518-hp, all-AMG V8 engine that’s coupled to a newly developed MCT transmission.
Featuring an innovative start-up clutch that replaces a conventional torque converter, the seven-speed MCT (for multi-clutch technology) transmission combines the direct connection of a manual gearbox with the lightning-quick automatic gear shifts of a Formula 1 race car. Topping off the SL chassis is an even more agile AMG sports suspension based on the Mercedes-Benz ABC active suspension.
MCT Transmission – The Best of Both Worlds
Providing the direct feedback of a manual transmission with the total convenience of an automatic, the new seven-speed MCT with AMG Speedshift is an all-new design available only in the new SL63 AMG. Featuring seven speeds, four shift modes and a double-clutching function, the MCT transmission offers impressive versatility and even faster shift times.
At the heart of the new AMG Speedshift MCT seven-speed sports transmission is a new start-up clutch, which runs in an oil bath and replaces a conventional torque converter. Thanks to its low rotational mass, the start-up clutch helps the transmission respond instantaneously and dynamically with no slip.
Fitted with four drive modes: “C” (Comfort), “S” (Sport), “S+” (Sport plus) and “M” (Manual), the transmission provides customized shift control for maximum driving pleasure, and does so with no interruption of power. In Comfort mode, smooth shifts coupled with a “soft” accelerator response are set up for silky smooth power transfer. In Sport mode, the engine and transmission interact quicker – upshifts and downshifts take place at higher engine speed. Gearshifts are around 20 percent faster than in Comfort mode. Switching to the Sport Plus mode cuts another 20 percent off shift times, while the sportiest mode, Manual, reduces shifting times by another 10 percent – a total reduction of 50 percent compared with Comfort mode. In Manual mode, the gearshifts take just 100 milliseconds.
Ultra-fast, spontaneous multiple downshifts are another forte of the new MCT sports transmission. For instance, kickdown will shift directly from seventh down to fourth gear or from fifth to second. In the “S” (Sport), “S+” (Sport plus) and “M” (Manual) modes, an automatic double-clutching function is active. Every manual or automatic downshift is accompanied by precisely metered double-clutching – from “S” through “S+” to “M” incrementally. Not only does double-clutching make driving more fun, but virtually load-free downshifting minimizes any jerking, a special benefit when braking into a curve.
The First Engine Developed From the Ground Up by AMG
The SL63 AMG is powered by an AMG 6.2-liter V8 engine that features four valves per cylinder, variable valve timing, bucket tappets (rather than rocker arms) and a variable intake manifold. Sharing no parts with Mercedes-Benz V8 engines, the 6.3-liter engine was a completely autonomous development at AMG.
Built almost completely from a high-strength silicon-aluminum alloy, the cylinder bores make use of a twin-wire-arc-sprayed (TWAS) coating, a process that results in impressively low friction and running surfaces that are twice as hard as conventional cast-iron cylinders.
The 6.3-liter engine block boasts an especially rigid bedplate acting as the overall support of the main bearings (similar to a one-piece set of main bearing caps), cast-in steel reinforcements and a sturdy closed-deck layout in the cylinder head area. The high-flow intake and exhaust ports form a vertical straight line, helping the 6.3 AMG engine rev freely to more than 7,000 rpm, yet the highly flexible AMG engine still produces nearly 90 percent of its peak torque at only 2,000 rpm.
A finely balanced crankshaft with six counterweights spins in five main crankshaft bearings. The crankshaft counterweights feature heavy metal plugs – a detail usually found only in racing engines – which means they can be significantly smaller, increasing power by reducing rotational inertia and oil drag.
Each forged connecting rod is precisely “cracked” with the help of a laser beam, so the irregular fracture contributes to its strength when the two halves are clamped around the crankshaft. The connecting rods and lightweight pistons are matched for extremely close weight tolerances that contribute to smooth running at high speeds. Small nozzles in the engine block spray cooling oil onto the underside of each piston crown.
“Bucket” Followers Instead of Rocker Arms
Twin overhead camshafts in each cylinder bank open the 32 valves via bucket-type followers. In other words, instead of rocker arms, the cam lobes sweep across the flat top of the followers, which sit directly on top of the valve stems. This space-saving design provides a very stiff valve train that allows for large valve openings and dependable high-speed operation for maximum horsepower and torque. However, in contrast to racing engines, each bucket incorporates a hydraulic lifter that automatically maintains valve clearance, which allows for long service intervals and low costs.
The AMG V8 makes use of variable intake and exhaust valve timing to maximize efficiency and torque over a wide RPM range. Valve timing can be automatically adjusted within a range of 40 degrees using electro-hydraulic vane-type adjusters on each camshaft. At part throttle, the valve timing adjuster keeps the exhaust valves open as the intake valves are opening, using this valve overlap for internal exhaust gas recirculation, reducing exhaust emissions and improving fuel economy. However, approaching full throttle, the camshaft adjustment optimizes valve timing for maximum power. The intake cams are driven by a double chain from the crankshaft, and small gears on the intake cams in turn drive the exhaust cams.
The SL63 Gets Unique Styling Touches
The SL63 comes with a distinctive AMG front hood that’s noticeably different from other SL models, as well as a new front apron with a more pronounced wedge shape, larger cooling air intakes, and a black grille. Bi-xenon headlights with black surrounds and large round fog lights ringed in chrome and set well to the side emphasize the vehicle’s width.
Hot air from the engine exits through side air outlets in the front fenders and from the “gills” behind the front wheels. Trim panels finished in matte silver with “6.3 AMG” lettering catch the eye, as do new outside mirrors with arrow-shaped LED turn indicators.
SL63 AMG body styling also includes deeper AMG side sill panels and a beefy-looking rear apron that incorporates a large black air diffuser and two pairs of chrome tailpipes. An AMG rear lip spoiler on the trunk lid reduces lift, especially at high speeds.
Finished in nappa leather and genuine carbon fiber, the interior features standard AMG sport seats, an AMG three-spoke steering wheel and a sport instrument cluster with red tach and speedometer needles that swing to the max position and back whenever the ignition is turned on.
Optional Performance Package for the SL63 AMG
An optional Performance Package is also available for the SL63 AMG, which includes even higher-performance components that are well suited for sporty-minded drivers:
· Top speed raised to 186 mph · Vented ceramic front brake discs that are 15.3 inches in diameter · Multi-disc limited-slip rear differential with a 40 percent locking factor of for enhanced traction · 19-inch AMG twin-spoke forged light-alloy wheels · Staggered-width tires: 255 / 35 R 19 in front and 285 / 30 R 19 at the rear · AMG high-performance suspension based on ABC active suspension · Smaller AMG sport steering wheel with a flattened underside and silver-aluminum shift paddlesv
AIRSCARF Around the Head and Neck
All 2009 Mercedes-Benz SL roadsters are now available with AIRSCARF, an innovative feature that can extend the open-air driving season into the cooler months. Another technological first from Mercedes, AIRSCARF is an extra heating system built into the driver and passenger seats. At the touch of a button, warm air flows from vents in the head restraints, acting as an invisible scarf around the head and neck.
Testing revealed that warming just a relatively small area around the neck dramatically improves comfort in cooler weather. The AIRSCARF neck-level heating system blows warm air from the head restraints of the driver and passenger seats, allowing occupants to cruise comfortably with the retractable hardtop open in colder weather. AIRSCARF uses a heating element made primarily of barium titanate, which heats up in a matter of seconds when electrical current is applied.
Optional on the V8-powered SL AMG model and standard on the SL65 AMG, the AIRSCARF neck-level heating system even compensates automatically for changes in air temperature and vehicle speed. AIRSCARF comes with a three-speed switch and an electronic control module that monitors data from the speedometer as well as from inside and outside temperature sensors. AIRSCARF automatically adjusts the fan speed based on this information, and at the same time, the switch can override the automatic settings.
New Audio Technology
With its 6.5-inch color display screen, the standard COMAND system with GPS navigation has been refined with a new MMI interface and a four gigabyte hard drive as well as an integrated six-disc CD-DVD player and a Music Register for around 1,000 MP3 tracks. The interface makes it easy to connect an iPod, USB stick, memory card and other devices. Music tracks can be indicated on the COMAND display located on the center console as well as a smaller display in the center of the instrument cluster, and they can be selected easily using the buttons on the multi-function steering wheel.
Any Bluetooth-enabled cell phone will work hands-free – even with the phone in a pocket or purse, the audio is automatically muted when a call is made or received, and callers are heard over the audio system speakers. In addition, phone address book info can be displayed by the COMAND system
From Coupe to Roadster in 16 Seconds
At the push of a button, the SL’s retractable hardtop can be fully opened or closed in just 16 seconds, transforming the car from a quiet, weather-tight coupe to a top-down open-air convertible. A hydraulic pump and 11 computer-controlled hydraulic cylinders power the system, and roof operation is controlled by a switch on the center console. A clever folding design allows for a surprisingly large cargo area of 7.2 cubic feet when the top is down. With the top up, the trunk holds 10.2 cubic feet.
The World’s Safest Convertible
Widely acclaimed as one of the world’s safest convertibles, the SL provides sports car performance with all the built-in safety that’s expected from Mercedes-Benz. Since an open car can leave its occupants vulnerable in a rollover, Mercedes engineers met the challenge in the SL with the world’s first automatic roll bar.
Normally part of the interior’s rear-compartment surround structure, the padded, leather-covered bar pops up, locking in place in a third of a second if sensors detect an impending rollover. The driver can also raise and lower the bar by a switch on the console.
Shoulder belts are integrated directly into the seats for greater occupant protection, especially in roll­overs. The Mercedes SL was also the first car with side airbags, which are part of a safety system that includes dual front airbags and emergency tensioning retractors that tighten the seat belts in a collision.

NOVITEC Ferrari F430 RACE ROSSO 707hp

The NOVITEC ROSSO two-seater is one of the world’s fastest and most powerful street-legal cars and starts at 193,277 Euros MSRP. At the heart of the snow-white racer featuring triple-design black stripes lies the NOVITEC ROSSO twin-supercharger engine in its latest evolutionary stage – RACE. Up to now, the eight-cylinder, four-valve engine with a displacement of 4,308 ccm and mechanical NOVITEC ROSSO twin superchargers produced 656 hp / 482 kW. For an additional 51 hp / 38 kW of power the components were again modified extensively. The two belt-driven superchargers were fitted with different turbine vanes and maximum boost pressure was increased to 0.48 bar. Two generously dimensioned intercoolers with their own supply of cooling water lower the temperature of the charge air for maximum power yield. The Ferrari engine is further fitted with an entirely new heat-insulated intake manifold with larger ports and high-performance air filters. A special air duct in the underfloor routes cooling air to the engine. The injection system is fitted with larger injection nozzles. On the exhaust side, low-pressure sport catalysts and the NOVITEC ROSSO stainless-steel high-performance exhaust system with electronically controlled flap ensure optimal gas evacuation. The electronic engine management coordinates the flawless interaction of the tuning components with newly programmed mapping for ignition, injection and on-board diagnostics, and ensures clean emissions that meet EURO IV limits. Enlarged cooling systems for water and oil guarantee the engine’s thermal health. Also contributing to the thermal well-being are the NOVITEC ROSSO exposed carbon-fiber breather grilles on the hood. The carbon-fiber engine bay cladding provides an attractive backdrop for the performance tuning. The NOVITEC ROSSO RACE twin-supercharger conversion, available for all Ferrari F430 coupes at a cost of 51,260 Euros, boosts maximum power output by 217 hp / 159.7 kW over the production engine. 707 hp / 520 kW at 8,350 rpm and a peak torque of 712 Nm at 6,300 rpm elevate the F430 RACE to a performance level attained only by a select few, markedly more expensive super sports cars. The sprint from rest to 100 km/h is shortened by half a second to 3.5 seconds. After just 10.5 seconds the car reaches 200 km/h. The 300-km/h barrier is shattered after 29.9 seconds. In combination with longer gear ratios available upon request the top speed grows from 315 km/h to 348 km/h. To be able to safely control this enormous performance potential at all times NOVITEC ROSSO also modifies aerodynamics, tires, suspension and brakes. Like all other body components the NOVITEC ROSSO front spoiler was developed in the wind tunnel. It is attached to the underside of the production front apron. It lends the F430 an even more aggressive frontal appearance and reduces lift on the front axle. The sides of the mid-engine sports car are refined with NOVITEC ROSSO rocker panels. The NOVITEC ROSSO rear diffuser is custom-tailored to the standard venturi tunnel and increases downforce on the rear axle. Upon customer request a rear wing can be added as well. Black-tinted taillights and lateral turn signals complete the sporty RACE looks. 20-inch wheels instead of the standard 19-inch wheels: The three-piece NOVITEC ROSSO NF3 double-spoke wheels in sizes 8.5Jx20 in front and 12Jx20 on the rear axle fill out the F430 wheel houses perfectly. High-performance tires in sizes 235/30 ZR 20 and 325/25 ZR 20 come from technology partner PIRELLI. Agile, safe handling is one of the strengths of the NOVITEC ROSSO sport suspension for the Ferrari, optimized everyday use the other. Contrary to the production suspension the front can be raised by 40 millimeters at the push of a button to safely navigate past curbs, driveway entries and speed bumps. Once the car reaches a speed of 80 km/h the suspension automatically lowers itself back to normal position, about 35 millimeters lower than the production car. NOVITEC ROSSO sport stabilizers reduce body roll and provide even more direct turn-in. The NOVITEC ROSSO high-performance brake system was developed in cooperation with Brembo. It features six-piston calipers with 380-mm vented and cross-drilled steel discs on front and rear axles. The brake delivers maximum stopping power and endurance. NOVITEC ROSSO also offers custom options for the interior of all Ferrari F430 models. The flattened bottom of the leather/carbon-fiber sport-steering wheel facilitates entering and exiting the vehicle. The longer NOVITEC ROSSO carbon-fiber F1-style shift paddles are easy to use even during fast cornering. Among the attractive accessories are also an elongated center console, carbon-fiber scuff plates and the NOVITEC ROSSO Supersport seats that can be custom-tailored to the driver’s body. Custom interiors can be crafted in any leather and Alcantara colors and designs

Acceleration 0-60 mph s:4.1
Top Speed mph (km/h):211 (340)

One of the world's fastest and most powerful street-legal BMW is made by G-Power. The 211-mph G-Power Hurricane is based on the latest BMW M5. At the heart of the high-performance sedan is a five-liter V10 engine with G-Power EVO II supercharging system that delivers 730 bhp.To achieve the desired increase in power output of 230 bhp for the fast-revving engine that normally produces 500 bhp, G-Power, in cooperation with ASA Automotive, has developed a high-tech supercharging system.

The system uses one belt-driven ASA T1-12 compressor for each cylinder bank. Contrary to conventional mechanical chargers that waste a large portion of the additional power on being driven themselves, the ASA compressor has an efficiency rate of up to 80 percent. The ASA charger is also small, which allows G-Power to install two of them in the tight confines of the M5 engine bay. With a maximum airstream volume of up to 1,200 kg per hour per cylinder bank the compressors are designed for an even higher power output. Boost pressure is limited to 0.5 bars.The pre-compressed charge air is cooled down in a highly efficient dual-flow water-to-air intercooler system that is mounted above the engine. This measure optimizes power yield and, in combination with a larger water-cooled oil cooler with pressure reservoir, also ensures the engine's thermal health. Specially developed mapping for engine electronics and SMG gearbox controls coordinate the perfect interaction of all new components.The inner workings of the four-valve ten-cylinder engine are optimized for even higher engine speeds with lightweight, precision-matched high-performance forged pistons from technology partner MAHLE. The supercharged V10 engine produces its maximum power output of 730 bhp between 7,500 and 8,200 rpm. The high efficiency rate of the two superchargers, each spinning at up to 100,000 rpm and more, results in a torque diagram that rises early and at 3,800 rpm already surpasses the production engine's peak torque of 383 lb-ft, delivered at 6,100 rpm. The new peak of 517 lb-ft is reached at 7,200 rpm.Acceleration performance benefits accordingly. With a sprint time from rest to 60 mph of 4.1 seconds the two-ton sedan bests its production counterpart by a few tenths. With approx. ten seconds to 124 mph the advantage grows to 5.0 seconds. The 186-mph (300 km/h) barrier is shattered in less than 29.5 seconds. Contrary to the production car the G-Power Hurricane is not limited electronically to a top speed of 155 mph. Aided by the specially cooled G-Power anti-slip differential the engine propels the car to a top speed of 211 mph.The enormous performance places extreme demands on aerodynamics, tires, suspension and brakes.The G-Power front apron, upon request also available made from especially light carbon fiber, replaces the production part in its entirety. Its large air inlets provide optimal supply of cooling air for all radiators and front brakes. At the same time the spoiler minimizes lift on the front axle at high speeds.The G-Power rocker panels smooth the airflow between the wheel houses and give the M5 and longer, lower and sleeker appearance. Lift on the rear axle is reduced by a spoiler lip attached to the trunk lid and the carbon-fiber rear diffuser for the G-Power rear apron.Even better driving dynamics and more exclusive looks are the hallmark of the G-Power Silverstone 21-inch light-alloy wheels that fill out the space beneath the wheel arches perfectly. The drop-center rims have brilliant-graphite coated centers while the outer rim wells and spokes are polished. They are mounted in sizes 9.5 J x 21 with size 255/30 ZR21 tires in front and size 10.5 J x 21 wheels with size 295/25 ZR21 tires on the rear axle.The large wheels make room for the G-Power high-performance brake system with six-piston fixed calipers and 400 x 36 millimeter brake discs on the front axle. G-Power also offers an upgrade package for the standard M5 brakes that consists of high-performance pads and brake fluid.The M5 handling can be made even sportier by installing the height-adjustable G-Power coil-over suspension RS with nine selectable settings each for bound and rebound.For upgrading the cockpit G-Power offers sporty components made from exposed carbon-fiber trim or an ergonomically shaped NARDO EDITION sport steering wheel covered in perforated G-Power Kjerba-Nappa leather that is a pleasure to touch.The G-Power Hurricane is available as a fully converted car starting at 240,000 Euros. Any existing M5 - sedan and wagon - can also be upgraded with the G-Power twin-compressor system, available for 89,000 Euros. The price includes all necessary modifications to suspension, brakes and wheels. Also available are any items from the extensive G-Power tuning accessories lineup.
