The Audi S4 is ready for the market launch, and this latest spy shots prove that we are right. The S4, sedan version, will make its world debut this autumn at the Paris Auto Show. The station wagon version will be launched at a later date, and the first prototypes are also on testings.
The V8 engine was dropped and replaced by a 3.0 liter V6 TFSI-engine, both turbo and direct injection, that delivers around 330 hp (there are rumors also saying there will be a 350 hp version.) The engine will be mated to a 7-speed S-tronic gearbox.
The new 3.0 TFSI engine makes its debut in the S4, and starting 2010 will be used in S5, and a detuned version that will produce around 300 hp will be used for the A6 and A7.
Audi will unveil the hot S4 sedan this autumn at the Paris Motor Show. It will be powered by a new supercharged V6 petrol engine producing around 350bhp.
The future S4 will feature the new S-tronic gearbox that weights 142kg - around 40 kilos more than the six-speed manual. However, performance is actually faster with the twin-clutch ’box and emissions are lower, too.
The 2009 S4 will make the 0 to 60 mph sprint in less than six seconds and will hit a top speed of 155 mph (electronically limited).
Sales will begin in early 2009. The S4 will be offered as sedan, station wagon and convertible. A RS4 version will also debut in 2009.
The next generation S4 will be unveiled in 2009 as a 2010 model. The super-sedan will be powered by a supercharged 3.0-liter V6 and will have enough power to compete with models like BMW 335i.
In 2011 Audi will also unveil a RS4 version, powered by a V8 engine. It will compete with M3.
The 2010 S4 will loose weight and will have improved fuel economy.
First rumors said the 2010 Audi S4 would share its powertrain with the S5. But this rumors are incorrect as the 2010 S4 will be powered by an all-new forced-induction 3.0-liter V-6 that will generate something close to the 340 hp.
The reason is quite simple: fuel economy. Audi’s strategy is to deliver comparable or improved overall performance by toeing the line on weight and maintaining power output by using forced induction on a smaller displacement engine. Doing so will boost a manual transmission S4’s fuel economy on the European cycle to 23.3 mpg compared with only 19.4 mpg for the V-8 S5. That’s an efficiency gain of 20%.
A less powerful, 290-hp, 310 lb-ft version of the engine will be the base offering in the A6 Quattro, replacing the 3.2-liter V-6. Known as TFSI, which in the past has been Audi’s internal moniker for four-cylinder turbos, the new engine may be referred to as the 3.0T in the model name, possibly indicating a twin-charged system using both a supercharger and a turbocharger. While Volkswagen has a “twincharger,” Audi has not yet offered such a system. At the very least, we expect the new V-6 to be supercharged, although what will allow the S4’s version to generate 50 or so more horsepower is still a mystery.
Audi will debut the 2010 S4 this autumn, probably at the Los Angeles Auto Show.
Some guys from Audiworld publish some pictures taken in Germany of what it looks is the Avant version of the Audi S4. The exterior is not the S4, but the brakes and the back kind of say it is.
According to some inside information from someone on Audi, the new S4 model will be powered by a 3.0 liter TSFI engine twin turbo, generation 330 hp. The time needed to make from 0-60 mph will be better that the 5.4 seconds from the actual model, dropping to a clean 5 seconds.
