Is this off the top of your head or do you have evidence to back this claim up. Also turbo cooling and engine doesnt matter but torque and power figures do. Have you raced them side by side? Regarding how power is put down - they both use the same haldex system.
Well these are the differences Audi provide over the A3 which obviously will include the 8L S3 too:
The power plant of the S3 delivers all that is expected of a powerful sports engine, and does so supremely well. The 2.0 TFSI, developed by AUDI AG, combines direct injection and turbocharger technology and delivers 195 kW (265 bhp) at 6,000 rpm. And at just 2,500 rpm it already musters up an impressive 350 Nm of torque this pulling power remains constant up to 5,000 rpm. In the combined driving cycle the 2.0 TFSI displays another welcome character trait, consuming just 9.1 litres of fuel over 100 km further proof of the forward-looking efficiency of TFSI technology developed by Audi.
Compared with the A3, this engine is an advanced version featuring fundamental changes. The new turbocharger with its enlarged turbine and compressor rotor generates 1.2 bar of boost pressure an unusually high figure. A modified intercooler significantly lowers the temperature of the compressed air, thus increasing the air mass that is necessary for combustion.
The new high-performance TFSI engine features pistons with stronger pins, while strengthened connecting rods with new bearings transmit the powerful forces to the crankshaft. The cylinder block has been reinforced, and the head is made of a new, highly heat-resistant alloy.
The exhaust camshaft timing has been adjusted to accommodate the increased power output. High-pressure injectors with an enlarged cross-section squirt the fuel straight into the combustion chamber.
For all its progressive technology, the high-performance turbo engine tips the scales at just 152 kilograms, less than comparable engines of direct competitors with a positive impact on the axle load distribution.
To go with its sporty nature and firm handling, the new Audi S3 has a six-speed, close-ratio manual gearbox. Gearshift travel has been reduced for the S3, permitting even sportier and more precise gear changes. As is the case for all
Audi S models, the new S3 drives all four wheels by means of quattro permanent four-wheel drive. An electronically controlled hydraulic multi-plate clutch, positioned at the rear for the benefit of weight balance, distributes the torque as needed delivering plenty of grip and maximum driving safety. All the drivetrain components have been strengthened to cope with the high level of engine torque.
In terms of handling, the Audi S3 exhibits all the qualities of a high-performance sports car; it responds immediately to steering movements and achieves high cornering speeds. The innately sophisticated suspension of the A3 with subframes front and rear, triangulated lower wishbones at the front and four-link suspension at the rear has been further refined.
The springs and shock absorbers have been given firmer ratings, with the result that the S3 sits 25 millimetres lower than an A3 with standard suspension. The pivot bearings and wishbones made from aluminium reduce the unsprung weight, further enhancing dynamic response and comfort. Stiffer suspension mounts and a sportier characteristic for the electromechanical steering provide even greater precision.
18-inch alloy wheels and 225/40 tyres ensure firm adhesion to the road surface. A 17-inch brake system with sports brake pads guarantees optimum deceleration; the black painted callipers bear the S3 logo at the front.
The extras also include a leather steering wheel with flat-bottomed rim and in the quattro GmbH range folding bucket seats. In the infotainment area, Audi is presenting a new generation of audio systems. The premium package is rounded off by universal interfaces for mobile phone and iPod, plus a sound system from Bose with eight high-performance speakers. Standard equipment includes deluxe automatic air conditioning, a driver information system with a new lap-timer function, and an anti-theft alarm. Front fog lights and xenon plus headlights with daytime running lights also underline the impressive price/performance ratio. The starting price of the 265 bhp Audi S3 in Germany is EUR 35,150.
