Audi A1

 Supermini sized economical car launched by Audi at the 2010 Geneva Motor Show. Sales of the initial three door A1 model started in Germany in August 2010, with the United Kingdom following in November 2010. A five-door version, called Sportback, was launched in November 2011, with sales starting in export markers during spring 2012.

The A1 is designed to compete with the Mini, and Alfa Romeo MiTo. The car is aimed mostly at young, affluent urban buyers.

The A1 is produced at Audi's Belgium factory in Forest, near Brussels.The A1 is based on the Volkswagen Group PQ25 platform, the same platform used in the SEAT Ibiza Mk4 and the VW Polo Mk5, and in its development Audi has collaborated with SEAT. The A1 uses a MacPherson strut front and torsion beam rear suspension.

The UK launch of the Audi A1 was held on 13 November 2010. The national launch took place from Battersea Power Station,where up to 300 Audi A1s left London.

The 100,000th A1 was produced in June 2011.[1

The A1 was previewed at the 2007 Tokyo Motor Show in the form of the Audi metroproject quattro concept car. The concept seats four and features a new hybrid powertrain. With this powertrain, a 1.4 L (85.4 cu in) 148 bhp (110.4 kW) Turbo FSI engine drives the front wheels via a six-speed S-Tronic, while a 40 bhp (29.8 kW; 40.6 PS) electric motor provides power to the rear wheels. The electric motor is also capable of producing 148 lb·ft (201 N·m) of torque.

The metroproject quattro is able to travel 62 miles (100 km) at up to 62 mph (100 km/h) on one charge of its lithium-ion batteries, which reduces fuel consumption by up to 15%. Both power sources are available to use simultaneously, with the driver then benefiting from McPherson strut front and four-link rear suspension configuration, electromechanical speed-sensitive power steering with a low energy draw, Audi magnetic ride adaptive damping technology, and 0 to 100 km/h (0 to 62 mph) in just 7.8 seconds.

At the 2008 Leipzig Auto Mobil International show, Audi again presented the metroproject quattro, renamed the A1 Project Quattro.[21] The vehicle was designed by Audi AG Project Designer in Exterior Design Dany Garand, who also presented the design during the car's Hong Kong debut.

A1 Sportback concept

Audi unveiled a second A1 concept car at the Paris Motor Show in October 2008. The A1 Sportback concept is a restyled five-door development of the metroproject quattro. Like the earlier concept, the A1 Sportback has a hybrid powertrain, with the same 1.4 L petrol engine and S-Tronic dual-clutch transmission, plus a 20 kW (27 hp), 150 N·m (110 lb·ft) electric motor. However the electric motor drives the front wheels, rather than the rear. Quoted 0 to 100 km/h (0 to 62 mph) acceleration is 7.9 seconds and average CO2 emissions are given as 92 g/km. The A1 Sportback retains the dimensions of the Metroproject quattro, except for a slightly greater length, at 3.99 m (157 in) .
A1 e-tron

The Audi A1 e-tron concept car is an electric variant of the A1, first shown at the 2010 Geneva Motor Show.[25] The A1 e-tron is a series plug-in hybrid (PHEV), powered by an electric motor with a continuous output of 45 kW (61 PS; 60 bhp), and a peak output of 75 kW (102 PS; 101 bhp). A fully charged 12 kWh lithium-ion battery gives a maximum range of 50 kilometres (31 mi), after which a 254 cc Wankel engine is used to power a 15 kW (20 PS; 20 bhp) generator with a 12 L (2.6 imp gal; 3.2 US gal) fuel tank.[26] This is estimated to provide an additional range of 124 mi (200 km).[25] The company claims the car weighs 1,190 kg (2,600 lb), can reach 62 mph (100 km/h) in 10.2 seconds and a maximum speed of 80 mph (129 km/h).

A field testing programme of twenty A1 e-tron vehicles began in Munich in late 2010.[28]

In June 2012, the UK's Car Magazine reported that Audi had put the production version of the A1 e-tron on hold indefinitely in order to slim down its future electric vehicles plan.  It was reported that, according to the director of e-mobility and sustainability strategy at Audi of America, the A1 e-tron had never been scheduled for production.
A1 clubsport quattro

In May 2011, the A1 clubsport quattro concept car was shown at the Wörthersee event. This car has a modified version of the Audi RS 3's five-cylinder 2.5 L engine tuned to 503 PS (370 kW) and 660 N·m (487 lb·ft). Capable of 0 to 100 km/h (0 to 62 mph) acceleration in 3.7 seconds, the car also features a restyled exterior including "blister"-style extended wheelarches reminiscent of the Audi Quattro and minimal, lightweight interior trim
