Audi TT quattro sport concept at 2014 Geneva Motor Show

Audi to present a truly special show car at the Geneva Motor Show. The Audi TT quattro sport concept embodies the dynamic potential of the new Audi TT in its purest form. Its two-liter TFSI® supplies 309 kW, which the car puts on the road via the quattro all-wheel drive. “With our Audi TT quattro sport concept show car, we wanted to demonstrate what the new TT’s technology can do if you take it a step further,” explains Prof. Dr. Ulrich Hackenberg, Board Member for Technical Development. “This car is designed for racing – an extreme driving machine for the motorsports enthusiasts among our customers.”

Powertrain

The engine in the Audi TT quattro sport concept makes a powerful statement. The 2.0 TFSI® has a power output of 309 kW at 6,700 rpm – a new benchmark in the two-liter category. Its specific output is 155 kW per liter of displacement – that’s more than even 2001’s victorious Le Mans R8 racing car, which was the first time Audi combined turbocharging with FSI® direct gasoline injection. The four-cylinder engine has 450 Nm of torque available in the engine speed range from 2,400 to 6,300 rpm. with over 300 Nm already available at only 1,900 revs.

At a curb weight of 1,344 kilograms, the Audi TT quattro sport concept is an athlete in peak condition. Each hp supplied by the two-liter TFSI®, which itself weighs under 150 kilograms, needs to shift less than 3.2 kilograms. The four-cylinder engine catapults the show car from 0 to 100 km/h in just 3.7 seconds.

Chassis

With its cutting-edge chassis – McPherson wheel suspension with aluminum components at the front and a four-link layout at the rear – the Audi TT quattro sport concept offers sharp, precise race car handling. The stiff setup brings the body closer to the road when compared with the series-production TT. 54 percent of the weight rests on the front axle, 46 percent on the rear. ESC electronic stabilization control, which can be partially or fully deactivated, complements the suspension’s sporty character.

When cornering, wheel-selective torque control kicks in. If necessary, drive torque is transferred from the wheels on the inside of the bend to those on the outside. Thanks to the distribution of torque, the car turns very slightly into the corner, helping the driver. This allows for precise and neutral cornering and the TT greatly increases its dynamism and stability.

Body

A significant part in the Audi TT quattro sport concept’s lightweight design is played by the body, which is based on the MQB modular transverse matrix. Its hybrid concept represents the latest evolution of the Audi Space Frame (ASF) and further lowers the car’s center of gravity compared with the second-generation series-production TT.

The front end is made of steel. The passenger compartment floor comprises high-strength, hot-shaped steel components which, thanks to their extremely high strength, feature very low wall thicknesses and thus weigh accordingly little. The compartment’s structure, the entire exterior skin, and the doors and lids are made of the classic Audi semi-finished aluminum products cast node, extruded profile, and sheet metal.

Exterior design

The flat Matrix LED headlights and the broad Singleframe grill dominate the study’s front end. The grill’s striking frame displays the quattro logo and holds the dark diamond-pattern grill.

Through their pronounced edges, the substantial air intakes – which also feature diamond-pattern grills – appear almost like inserted airboxes. They thus illustrate a key element in the new Audi TT’s design language: elements like the greenhouse and wheel arches create the impression of being individual bodies, thus producing the typical tension. The show car rests on 20-inch wheels with a central locking mechanism and semi-slick tires.

A splitter made of carbon-fiber reinforced polymer (CFRP) stretches toward the front to round off the front end at the bottom and increase the downforce on the front axle.
Interior design

The show car interior has been reduced to the essentials, doing away with numerous components that are dispensable on the race circuit. The door panels have been stripped of armrests and speakers – the interior is characterized by Alcantara. A dominant diagonal strip of Alcantara acts as a door pull handle, the door openers feature a filigree design. Low-set racing buckets serve as seats, featuring black four-point seat belts with white accentuating stripes. The luggage compartment offers space for two racing helmets.
The same as in the series-production TT, the controls are designed purely for the driver. The Audi TT quattro sport concept’s pilot has his hands on a compact steering wheel with a pronounced rim that flattens out at the bottom. The steering wheel’s spokes house the red start/stop button alongside the keys and rotary buttons for operating the Audi virtual cockpit. Depending on what the driver sets, the fully digital instrument cluster’s 12.3-inch display shows different views.
