Mercedes SLS Class R231 – Lamborghini super car – luxury Rolls Royce wallpapers

In December 2011, Mercedes-Benz announced the all new SL-Class and was formally launched at the North American International Auto Show in January 2012. The new SL (R231) has been produced for the first time almost entirely from aluminium. The new aluminium body shell weighs around 110 kilograms less than it would using the steel technology from the predecessor. Although the Mercedes-Benz SL-Class has more assistance systems on-board than its predecessor and therefore does actually sacrifice some of the weight saved through the aluminium body shell, the scales show some better figures: the SL 500 (1,785 kg) weighs around 125 kg (276 lb) less and the SL 350 (1,685 kg) is 140 kg (309 lb) lighter than its predecessor.

New features include the unique FrontBass system (it uses the free spaces in the aluminium structures in front of the footwell as resonance spaces for the bass loudspeakers) and adaptive windscreen wipe/wash system MAGIC VISION CONTROL, which supplies water from the wiper blade as required and depending on the direction of wipe. The R231 is also available with two different suspension systems: semi-active adjustable damping as standard. The optional active suspension system ABC (Active Body Control) is available as an alternative. Both suspension variants are combined with a new electromechanical Direct-Steer system featuring speed-sensitive power steering and a ratio that can be varied across the steering wheel angle and it also reduces the amount of steering required when parking and manoeuvring.

Contrasted with its predecessor, the new generation of the SL is longer and wider. Shoulder room is increased by 37 mm (1.5 in)) and elbow room 28 mm (1.1 in). porsche wallpapers, super car, subaru wallpapers, Mercedes SLS Class wallpapers, bentley wallpapers

(Ferrari F430)430 Scuderia
Serving as the successor to the Ferrari 360 Challenge Stradale, the 430 Scuderia (scuderia meaning “stable” , but also used in the context of motor racing teams, including Ferrari’s own) was unveiled by Michael Schumacher at the 2007 Frankfurt Auto Show. Aimed to compete with cars like the Porsche RS-models and the Lamborghini Gallardo Superleggera (superleggera meaning super light weight), it is lighter (by 100 kg (220 lb)) and more powerful (510 PS (375 kW; 503 hp) at 8,500 rpm and 471 N?m (347 lb?ft) of torque at 5,250 rpm) than the standard F430. Increased power comes from a revised intake, exhaust, and an ion-sensing knock-detection system that allows for a higher compression ratio] in the engine. Thus the weight-to-power ratio is reduced from 2.96 kg/hp to 2.5 kg/hp. In addition to the weight saving measures, the Scuderia semi-automatic transmission gained improved “Superfast”, known as “Superfast2”, software for faster 60 millisecond shift times. A new traction control system combined the F1-Trac traction from the 599 GTB and stability control with the E-Diff electronic differential. The Ferrari 430 Scuderia accelerates from 0-100 km/h (62 mph) in 3.6 seconds, with a top speed of 198 mph (319 km/h).

Although the 430 Scuderia was not available with a manual transmission, a Texas based tuning company fitted a 430 Scuderia with a manual transmission sourced from Ferrari thus making it the only example in the world to have a manual transmission.
