The Audi e-tron is based on the e-tron quattro concept that was unveiled at the 2015 Frankfurt Motor Show. The final production version was revealed in San Francisco on 17 September 2018, and it publicly debuted at the 2018 Paris Motor Show.
Scheduled for deliveries in Europe by December 2018, it got delayed to 2019 (customers reported expected delivery dates close to the end of 2019 – see the paragraph below); the car’s certification in Germany by the KBA (Federal Motor Transport Authority) was not obtained until required changes were made to the car’s software. In January of 2019, US market deliveries were due to commence in June. pagani wallpapers, supercars wallpaper, bugatti wallpapers, Audi E-Tron wallpapers, porsche wallpapers
(Porsche Cayman)All 986 and 987 Boxsters use the M96, a water-cooled, horizontally opposed (“flat”), six-cylinder engine. It was Porsche’s first water-cooled non-front engine. In the Boxster, it is placed mid-engine, while in the 911, rear-engine. The flat, mid-engine layout provides a low center of gravity, near-perfect weight distribution, and neutral handling. The engines had a number of failures, resulting in cracked or slipped cylinder liners, which were resolved by a minor redesign and better control of the casting process in late 1999. A failure for these early engines was a spate of porous engine blocks, as the manufacturer had difficulty in the casting process. In addition to causing problems with coolant and oil systems mingling fluids, it also resulted in Porsche’s decision to repair faulty engines by boring out the cast sleeves on the cylinders where defects were noted in production and inserting new sleeves rather than scrapping the engine block. Normally, the cylinder walls are cast at the same time as the rest of the engine, this being the reason for adopting the casting technology.
The model received a minor facelift in 2002. The plastic rear window was replaced by a smaller glass window. The interior received a glove compartment, new electro-mechanical hood and trunk release mechanism (with an electronic emergency release in the fuse box panel) and an updated steering wheel. Porsche installed a reworked exhaust pipe and air intake. In addition, the front headlight’s amber indicators were replaced with clear indicators. The rear light cluster was also changed with translucent grey turn signals replacing the amber ones. The side marker lights on the front wings were changed as well from amber to clear, except on American market cars where they remained amber. The bumpers were also changed slightly for a more defined, chiseled appearance, and new wheel designs were made available. Porsche Cayman wallpapers#Pontiac #Chevrolet #mitsubishi #AudiRS4 #AudiRS3
