Three New Models from Audi to be Shown at the Frankfurt Motor Show

INGOLSTADT, GERMANY - August 31, 2009: Audi will unveil three new vehicles at Frankfurt’s International Motor Show (IAA): the dynamic S5 Sportback, the low-emission A4 3.0 TDI clean diesel quattro, and the ultra-efficient A3 1.2 TFSI. These innovative engines boast differing concepts, yet share one thing in common: they embody Audi’s conviction that dynamics and efficiency are not mutually exclusive; on the contrary, they go hand in hand and are mutually complementary.

Elegant and dynamic: Audi S5 Sportback
The S5 Sportback is the pinnacle of the new Sportback model line.

This new five-door coupé is powered by a three-litre V6 with a mechanical compressor. With a displacement of 2,995 cm3, the small turbo engine delivers 245 kW and 440 Nm of torque between 2,900 and 5,300 rpm. The S5 Sportback sprints from 0 to 100 km/h in 5.4 seconds; its top speed of 250 km/h electronically limited. It averages just 9.7 litres of fuel per 100 km — the best in this power-output category.

A seven-speed S tronic dual-clutch transmission and quattro permanent all-wheel drive are standard equipment. An optional sport differential is also offered which variably distributes power on the rear axle between the rear wheels. This new model features 18-inch aluminium wheels fitted with 245/40 tyres and black brake calipers bearing S5 emblems at the front. Speed-dependent servotronic steering is also standard.

Small yet striking exterior and interior features visually distinguish the Audi S5 Sportback. Equipment highlights include electrically adjustable S sports seats covered with Silk Nappa leather.

Extremely clean: Audi A4 3.0 TDI clean diesel quattro
Audi debuted the 3.0 TDI clean diesel engine in its large Q7 SUV; now, the world’s cleanest diesel technology will also be available in the best-selling A4.

A package of technologies boasts an array of innovative solutions for engines and the after-treatment of exhaust gas.

At the engine, a new common-rail injection system (which generates up to 2,000 bars of pressure), innovative pressure sensors in the combustion chamber, and an especially high-performance exhaust re-circulating system collectively ensure a highly efficient and low-emission combustion process. A novel DeNOX catalytic converter, integrated within the end of the exhaust system, reduces residual nitrogen oxides. Just upstream of it, a pump injects an additive named AdBlue into the hot exhaust flow; there, this aqueous solution decomposes into ammonia — which splits the nitrogen oxides into nitrogen and water.

The A4 3.0 TDI clean diesel quattro already complies with the emission limits of the EU’s Euro 6 standard, expected to become law in 2014. It is also very fuel-efficient, averaging just 6.7 litres (Avant: 6.8 litres) of fuel per 100 km. The TDI engine is also a powerful performer, needing 6.2 seconds (Avant: 6.3 seconds) to go from zero to 100 km/h. Top speed is electronically governed to 250 km/h.

In conjunction with a six-speed tiptronic and quattro permanent all-wheel drive, this vehicle guarantees a high degree of comfort and superior traction.

Efficient Downsizing: Audi A3 and A3 Sportback 1.2 TFSI

Downsizing is a cornerstone of Audi’s efficiency strategy. The A3 model line will soon see the introduction of yet another turbocharged petrol engine featuring lower displacement. It unites maximum performance with minimum consumption.

Designed from new, the 1.2 TFSI generates 77 kW from a displacement of 1,197 cm3 . And as is typical of Audi, turbocharging and direct fuel injection once again perfectly comprise a technological one-two punch. Thanks to an aluminium crankcase, this four-cylinder engine weighs just 89.5 kilograms; this remarkably low weight also boosts its efficiency.

The 1.2 TFSI has been optimised to minimise friction. Eight valves are actuated by a single camshaft. A common-rail system injects the fuel. An electric control valve operates the turbocharger’s wastegate valve; boost pressure builds up spontaneously and scavenging losses drop.

This small engine generates 175 Nm of torque between just 1,500 and 3,500 rpm. It propels the three-door A3 1.2 TFSI from 0 to 100 km/h in 11.1 seconds; the Sportback, in 11.3 seconds. Both versions reach a top speed of 190 km/h and, on average, consume just 5.5 litres of fuel per 100 km — emitting just 127 grams of CO2 per kilometre.

European sales of the A3 and A3 Sportback 1.2 TFSI will begin in the first quarter of 2010. The new engine will initially be paired with front-wheel drive and a six-speed manual transmission.
