Audi A3 revealed with Tornado Line design

With the launch of the A3 Sedan this spring, Audi is entering the world’s largest market segment, the class of compact sedans. The dynamic four-door car offers all of the strengths of the A3 model series – with low weight thanks to lightweight design, powerful and highly efficient engines and numerous high-end solutions for infotainment as well as driver assistance systems. The top model of the series is the S3 Sedan with 221 kW (300 hp).

Body

With a 1.4 TFSI engine, the sedan has a curb weight of just 1,250 kg (2,755.78 lb). Audi uses many hot-shaped steel parts in the passenger compartment for low weight and maximum strength, while the engine hood is made of aluminum. The body is very rigid, crash-safe and quiet.

The strict dictate of lightweight design carries over into the interior and the engines as well. The four-cylinder engine weighs just over 100 kg (220.46 lb).

Powertrain

When the Audi A3 Sedan launches in Germany and Europe, the engine line-up will consist of three four-cylinder engines. Completely redesigned, the engines bring together efficiency technologies from Audi – direct fuel injection, turbocharging, innovative thermal management and the start-stop-system. The line-up of engines and transmissions will grow further, and will include two new basic engines.

The 2.0 TDI produces 110 kW (150 hp) and develops 320 Nm (236.02 lb-ft) of torque. It accelerates the A3 Sedan from 0 to 100 km/h (62.14 mph) in 8.7 seconds and takes it to a top speed of 220 km/h (136.70 mph). Its combined fuel consumption is 4.1 liters per 100 km (57.37 US mpg) – for a CO2 equivalent of 108 grams per km (172.20 g/mile).

Key performance parameters of the 1.4 TFSI are 103 kW (140 hp) and 250 Nm (184.39 lb-ft). At low engine load, the COD (cylinder on demand) system deactivates two cylinders. The 1.4-liter engine gives the car a combined fuel consumption of just 4.7 liters fuel per 100 km (50.05 US mpg); its CO2 emissions are 109 grams per km (175.42 g/mile). It takes just 8.4 seconds to accelerate from 0 to 100 km/h (62.14 mph), and the car’s top speed with this engine is 213 km/h (132.35 mph).

The 1.8 TFSI produces 132 kW (180 hp) and 250 Nm (184.39 lb-ft) of torque. It utilizes an extensive package of high-end technologies, including dual injection into the combustion chambers and the induction manifold. It enables sporty performance, taking 7.3 seconds for the standard sprint to 100 km/h (62.14 mph) and reaching a top speed of 235 km/h (146.02 mph). Its combined fuel consumption is 5.6 liters per 100 km (42.00 US mpg), equivalent to 129 grams CO2 per km (207.61 g/mile).

Depending on the engine, either a manual six-speed transmission or the S tronic is used. The dual-clutch transmission shifts the gears without any noticeable break in propulsive power. It is controlled by either the selector lever or paddles on the steering wheel.

The D shifting map is laid out for maximum fuel efficiency, while the rev levels are somewhat higher in the sporty S mode. In cooperation with the Audi drive select vehicle dynamics system, the S tronic offers a free-wheeling function in its efficiency mode which further reduces fuel consumption.
