Audi A1 First Driving Video Released
The Audi A1 supermini had its online media debut earlier this month. Since then, Audi has followed up with a new video that gives us a first glimpse of the A1 on the road in motion. While they have our attention Audi wants to emphasize the A1's agility. Audi Head of Chassis Development, Dr. Horst Glaser, enlisted the help of Audi DTM pilot Markus Winkelhock to take the dimunitive Audi for a spin.
In the front-wheel driven A1, the front suspension is a MacPherson strut layout with triangular lower control arms while the rear axle features a torsion-beam suspension with separated springs and shocks. Depending on the engine, between 61 and 63 percent of the weight rests over the front axle. Audi states this is a low value for a compact car.
For a more direct steering response, the A1 comes standard with electrohydraulic power steering which has a 14.8:1 steering ratio. ESP is also standard with an electronic axle differential lock, which sends light braking pulses to the slipping inside wheel during a curve.
Audi A1: Pure driving experience
- Direct-ratio, electrohydraulic power steering
- ESP stabilization system with electronic axle differential lock
- Winkelhock: "Benchmark in the small compact class!"
Ingolstadt, February 26, 2009 - With its agile handling and direct steering, the new Audi A1 is just a lot of fun. Dr. Horst Glaser, Head of Chassis Development at AUDI AG, tested the A1 together with DTM pilot Markus Winkelhock. The verdict was as follows:
The new Audi A1 offers a very sophisticated chassis, balanced weight distribution and a low center of gravity. "That is a guarantee for maximum driving enjoyment," says Horst Glaser, Head of Chassis Development at AUDI AG. Because it connects the driver to the road, the steering is one of the most important components of a sporty car. The A1 therefore comes standard with electrohydraulic power steering that has a very direct 14.8:1 steering ratio and is also more efficient than a purely hydraulic
system.
Another factor for the agile and safe handling of the A1 is the perfect tuning of the front axle bearings, the stabilizer bars, the springs and the dampers. The rear axle features a torsion-beam suspension with the springs and dampers separated. "The
car is very well sprung. It swallows up bumps of almost any size without any amplification of the motions," says DTM pilot Markus Winkelhock when describing his impressions.
One new Audi technology is on board every version of the A1 - the ESP stabilization system with an innovative electronic axle differential lock. The brakes are applied slightly to the inside wheel in a curve, allowing more torque to be transferred to the
wheel on the outside of the curve. The vehicle is very agile and the handling remains neutral even longer.
"After driving the Audi A1 for the first time, my opinion is clear: It's the benchmark in the small compact class," says Winkelhock.
