Audi at Frankfurt Motor Show
Audi's new S5 Sportback
30th August, 2009
Audi will unveil three new vehicles at Frankfurt’s Motor Show (IAA):
the remarkably dynamic S5 Sportback, the extremely low-emission A4 3.0 TDI clean diesel quattro, and the especially
efficient A3 1.2 TFSI. These innovative engines boast some very different key data, yet they share something 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 dynamics: Audi S5 Sportback
The S5 Sportback is the pinnacle of the new Sportback model line. This elegant, five-door coupé is propelled by
a three-litre V6 with a mechanical compressor. From a displacement of 2,995 cc, the small turbo engine delivers 245
kW and 440 Nm of torque between 2,900 and 5,300 rpm. The Audi S5 Sportback sprints from 0 to 100 km/h in 5.4
seconds [provisional figure]; its top speed of 250 km/h is limited by an electronic governor. It averages just 9.7
litres of fuel per 100 km [provisional figure] — the best in this power-output category.
Concerning the powertrain, the Audi S5 Sportback similarly underscores its superiority: a seven-speed S tronic
dual-clutch transmission and quattro permanent all-wheel drive are standard equipment. Upon request, Audi will
include the sport differential. It variably distributes power on the rear axle between the rear wheels. This new
“top model” has a sportily configured chassis with 18-inch aluminium wheels fitted with 245/40 tyres; black brake
callipers bear 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. Sales of the Audi S5
Sportback will start by mid-2010 in European countries. An Australian release is likely in late 2010.
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
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 recirculating 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 only 6.7 litres (Avant: 6.8 litres) of
fuel per 100 km. And this TDI engine is indeed a powerful performer, needing only 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 — and Audi is relentlessly committed. The A3 model
line will soon introduce yet another turbocharged petrol engine featuring lower displacement. It unites maximum
performance with minimum consumption.
Designed from scratch, the new 1.2 TFSI generates 77 kW from a displacement of 1,197 cc. And, as is typical of
Audi, turbocharging and direct petrol injection once again perfectly comprise a technological one-two punch.
Thanks to an aluminium crankcase, this four-cylinder engine weighs just 89.5 kilogrammes; 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 (42.77 mpg) — emitting 127 grammes of CO2 per
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.
