Audi A1 Concept Sportback: five hybrid compact car
After three Showcar Audi A1 project quattro from the Tokyo Motor Show 2007 is now a five-four-seater.
Small cars with hybrid system
Audi invented the car for the Subkompaktklasse - possibly to the expression of small cars to avoid. But in this category include the car. With 3.99 meters, 1.40 meters in height and 2.46-meter wheelbase, it has similar effects as the Polo. Unusually for the small class is the drive because the car is not a micro hybrid with start-stop automatic, but a plug-in Vollhybrid. It combines an Audi 1.4-liter TFSI engine with 150 hp with a 20 kW (27 hp) electric generator. The internal combustion engine transmits its power through dual-clutch gearbox S tronic to the front wheels. The electric motor during acceleration delivers up to 150 Newton meters additional torque. To clean the thrust also on the road to bring complements the front-wheel drive Audi is a newly developed, the ESP-driven front axle Quersperre.
Even purely electric drive
Apart from the supporting role in accelerating the electric motor is also capable of the small cars to power purely electric. The lithium-ion batteries allow emission-free range of up to 100 kilometers. The recharging can be done at each outlet. Also wins the car braking energy back to what it described as a recuperation. Thus, as well as through the start-stop automatic and the purely electric propulsion reduces the consumption compared to operating with the internal combustion engine, according to Audi by nearly 30 percent.
As sparingly as a diesel 
To limit itself to the small manufacturer Audi with 3.9 liter of super to 100 kilometers, representing a CO2 emission of 92 grams per kilometer correspond. This makes the car more economical than all other small cars with gasoline engines. Compared with Dieseln impressed with the hybrid-A1, but barely. For example the VW Polo BlueMotion comes to 3.8 liters of diesel per 100 kilometer. However, when the driving übertrumpft of the new Audi lean VW model significantly. The standard sprint to 100 km / h managed the Ingolstadt in 7.9 seconds, while the savings for polo takes 12.8 seconds. The maximum speed of 200 km / h was also far beyond the capabilities of the small Wolfsburg.
Sporty exterior
Apart from the hybrid system, the study gives an outlook on the planned Audi small car. The design builds on the three study Audi A1 project quattro from the year 2007. The vergitterte giant grill of the three has a kind of square aperture made. The B-pillars are hidden behind a Überglasung. Back there as in the Tokyo study, a roof spoiler.
