What do you call a high-performance sports car that's also a roadgoing vehicle with bloodlines that trace back to a three-time LeMans winner?

The Audi 'Le Mans quattro’ concept study.

The automaker unveiled the impressive vehicle at the 2003 Frankfurt Motor Show. With its Jet Blue paint finish and a wide stance, the Le Mans quattro has a bullish appearance on the road, says Audi.

At 1.90 metres wide but only 4.37 metres long and 1.25 metres high, the proportions are "pure sports car." A wheelbase of 2.65 metres accommodates a cockpit and the V10 'biturbo’ engine with FSI direct fuel injection, behind it. To the rear of the doors, between the sill and the roof, a large outward-curving intake supplies the needed air to the V10 engine, brakes, oil cooler and the turbo intercooler.

The trapezoidal shape of the Audi single-frame grille is flanked on the right and left by additional large air inlets. Their upper ends are flush with the flat-strip LED headlights, which have clear-glass covers. The centre of the bonnet curves up above the line of the front wings, which spread out at the sides over the large round wheel arches in a manner typical of Audi racecars.

The cockpit architecture is oriented toward the driver’s needs, and dominates the car’s interior, according to Audi. The driving position is integrated into the space between the instrument panel (with its changeover display graphics) and the centre console. Audi says the LeMans quattro car offers "generous" interior space for both occupants.

An aluminium Audi Space Frame (ASF) forms the central structure of the concept study. The outer skin and add-on parts use a weight-saving mixed aluminium and carbon-fibre concept , which Audi says provides optimal structural strength as well as a low weight of 1530 kg, thus providing a "foundation for top road dynamics."

This mid-engined two-seater is powered by a five-litre V10 'biturbo’ engine with FSI direct fuel injection, developing more than 602 horsepower at 6,800 rpm. Audi says the engine boasts considerable 'bite’, with seemingly inexhaustible power reserves even at very low engine speeds. The maximum torque of more than 553 lbs.ft is available from 1,750 rpm up to 5,800 rpm. A sequential-shift 6-speed gearbox allows the driver to use the torque in the appropriate doses. The Audi Le Mans quattro accelerates from 0 to 100 km/h in just 3.7 seconds and to 200 km/h in 10.8 seconds.

As its name indicates, the Audi LeMans quattro is equipped with Audi's permanent four-wheel drive system, which distributes the power variably (based on a 40:60 ratio) to the front and rear axles, giving the sports car its optimum road dynamics.

Double wishbone suspension is used at the front and rear. Firm basic suspension settings have been chosen to ensure the most effective road dynamics. Nevertheless, the innovative Audi 'magnetic ride’ shock absorbers ensure a high level of ride comfort.

With specs like that, the Audi LeMans quattro concept is a healthy competitor for the recently introduced Mercedes SLR McLaren (in New Models). Will it make it to production? No "official" word yet, but keep your fingers crossed ...
