Second generation (Typ 8P, 2006-2012)
The second generation Audi S3 - Typ 8P, is powered by a modified and uprated Volkswagen Group-sourced 2.0L Turbocharged FSI petrol engine, with a maximum output of 195 kW. As with all Audi S models, the design was done in-house by quattro GmbH. The engine features uprated high performance pistons, revised boost/fuel mapping, increased turbocharger size (KKK K04) and larger intercooler. The most powerful form of this widely used engine, and quattro four-wheel drive, makes for a 0 - 100 km/h time of 5.5 s, and an electronically limited top speed of 250 km/h.
The chassis has had the spring rating and dampers revised, along with the body kit. Like its predecessor, although badged a "quattro" model, the S3 does not employ a Torsen centre differential (as in other common quattro models), but instead uses the Swedish Haldex Traction system in its on-demand four-wheel drive transmission, due to the transverse engine layout.
In the United Kingdom, the S3 is priced notably higher than many of its rivals. BMW's 130i M Sport offers 265 bhp, but is slower to 100 km/h at 6.0 seconds. Other cars of similar power are a good deal cheaper; the Volkswagen Golf Mk5 R32 sports 184 kW, with 0 - 100 km/h achieved in 6.2 seconds. The Vauxhall Astra VXR comes with less power - 240 bhp - but manages 0 - 100 km/h in 6.5 seconds, whilst the SEAT León Cupra (2.0 T-FSI with 177 kW), Volvo C30 (225 bhp 2.5-litre inline-5 turbo), and Mazdaspeed3 (2.3-litre turbocharged engine with 263 bhp) also provide competition. Only the S3 and R32 are four-wheel drive, however, though the 130i M Sport is rear-wheel drive.
Audi has stated the S3 will not be sold in North/South America, although it is available in Mexico. Reasons range from pricing and competition with the Volkswagen Golf R32, and/or stealing sales from the new Audi TT and due to cost effectiveness in the North American market. Audi has announced a 2.0T quattro model for the North/South American market due out in 2009/2010 to coincide with the A3 body upgrade.
Audi S3 Sportback
In April 2008, Audi announced a five-door S3 variant based on the A3 Sportback (Typ 8PA), with the same engine and transmission as the existing 8P S3.[2]
At the same time a minor facelift of the 3-door S3 (in common with the A3) was also announced.[3]
