With a wheelbase measuring 2.6 m (102 in), the lengths of the overhanging front and rear bodywork was minimal. The track measured 1,364 mm (54 in) at the front, and 1,377 mm (54 in) at the rear.
The suspension incorporated rack and pinion steering and MacPherson strut suspension at the front, and semi-trailing arm type independent suspension at the rear. The rear suspension design causes camber changes, which can introduce “snap oversteer” at the handling limits. The power assisted brakes were discs on the front wheels, while the rear wheels had drum brakes (except the 323i model which had discs all round).
Model year changes
At the E21’s release, three models were available: with 316 (1.6-litre), 318 (1.8-litre) and 320 (2.0-litre) versions of the BMW M10 four-cylinder engine. To differentiate between models, the 320 model came with dual headlights, while the 316 and 318 had single headlights. lambo wallpapers, lamborghini, lotus wallpapers, BMW 3 Series wallpapers, koenigsegg wallpapers
(Porsche 987)Boxster Spyder
On 5 November 2009, Porsche officially announced the creation of a new variant of the Boxster, which was officially unveiled at the 2009 Los Angeles Motor Show. Positioned above the Boxster S, the Boxster Spyder was the lightest Porsche on the market at the time, weighing 2,811 pounds (1,275 kg), 176 lb (80 kg) lighter than a Boxster S. This was achieved through the elimination of the conventional soft top’s operating mechanism, the radio/PCM unit, door handles, air conditioning, storage compartments, cup holders and large LED light modules on the front fascia. Although some of these could be re-added to the car in the form of options. Weight saving was also gained using aluminum doors, an aluminum rear deck and the lightest 19-inch wheels in the Porsche pallet. The vehicle rides on a firmer suspension than the other Boxster models, and is almost one inch lower in order to have improved handling. A manually operated canvas top, carbon fiber sports bucket seats and two signature humps running along the back of the vehicle provide characteristic design elements. It is powered by a six-cylinder boxer engine with 320 hp (239 kW; 324 PS) and 273 lb?ft (370 N?m) of torque, a 10 hp (7.5 kW) increase in power over the Boxster S and the related Cayman S. The Boxster Spyder came with a 6-speed manual transmission as standard and had Porsche’s 7-speed PDK dual-clutch gearbox available as an option. The vehicle was released worldwide in February 2010 as a 2011 model with a base price of US$61,200. Porsche 987 wallpapers#Porsche #Mercedes #AudiQ7 #maserati #AudiRS3
