Prior to the introduction of the Audi 80 and Audi 50 in 1972 and 1974, respectively, Audi had led the development of the EA111 and EA827 inline-four engine families. These new power units underpinned the water-cooled revival of parent company Volkswagen (in the Polo, Golf, Passat and Scirocco), whilst the many derivatives and descendants of these two basic engine designs have appeared in every generation of VW Group vehicles right up to the present day.
In the 1980s, Audi, along with Volvo, was the champion of the inline-five cylinder, 2.1/2.2 L engine as a longer-lasting alternative to more traditional six-cylinder engines. This engine was used not only in production cars but also in their race cars. The 2.1 L inline five-cylinder engine was used as a base for the rally cars in the 1980s, providing well over 400 horsepower (300 kilowatts) after modification. Before 1990, there were engines produced with a displacement between 2.0 L and 2.3 L. This range of engine capacity allowed for both fuel economy and power.
For the ultra-luxury version of its Audi A8 fullsize luxury flagship sedan, the Audi A8L W12, Audi uses the Volkswagen Group W12 engine instead of the conventional V12 engine favored by rivals Mercedes-Benz and BMW. The W12 engine configuration (also known as a “WR12”) is created by forming two imaginary narrow-angle 15? VR6 engines at an angle of 72?, and the narrow angle of each set of cylinders allows just two overhead camshafts to drive each pair of banks, so just four are needed in total. The advantage of the W12 engine is its compact packaging, allowing Audi to build a 12-cylinder sedan with all-wheel drive, whereas a conventional V12 engine could have only a rear-wheel drive configuration as it would have no space in the engine bay for a differential and other components required to power the front wheels. In fact, the 6.0 L W12 in the Audi A8L W12 is smaller in overall dimensions than the 4.2 L V8 that powers the Audi A8 4.2 variants. The 2011 Audi A8 debuted a revised 6.3-litre version of the W12 (WR12) engine with 500 PS (370 kW; 490 hp). volvo wallpapers, lamborghini wallpaper, nissan wallpapers, Audi wallpapers, mclaren wallpapers
(Toyota Hilux)The Toyota Hilux (stylized as HiLux and historically as Hi-Lux) is a series of light commercial vehicles produced and marketed by the Japanese automobile manufacturer Toyota. The majority of these vehicles were sold as pickup truck or cab chassis variants, although they could be configured in a variety of body styles. Most countries used the Hilux name for the entire life of the series, but in North America, the Hilux name was retired in 1976 in favor of Truck, Pickup Truck, or Compact Truck. In North America, the popular option package, the SR5 (Sport Rally 5-Speed), was colloquially used as a model name for the truck, even though the option package was also used on other Toyota models, like the 1972 to 1979 Corolla. In 1984, the Toyota Trekker, the camper version of the Hilux, was renamed the 4Runner in Australia and North America, and the Hilux Surf in Japan. In 1995, Toyota introduced a new pickup model, the Tacoma, in North America, thus discontinuing the Hilux/Pickup. The 4Runner is now a full SUV, and the more recent models of the Hilux are separate in appearance from the Tacoma. Toyota Hilux wallpapers#BmwX5 #RangeRover #BugattiVeyron #Mitsubishi #AudiRS3
