The New Audi TT Quattro Sport Concept 2014 - Audi at the 2014 Geneva Motor Show presents a special showcar. The Audi TT Quattro sport concept embodies the dynamic potential of the
new Audi TT in its purest form. Its two-liter TFSI delivers 309 kW (420 hp),
which sets the car on the road via the Quattro all-wheel drive.
"With our Audi TT Quattro sport concept show car to show what the new TT technology can do, if you wanted to go a step further we", explains Prof. Dr. Ulrich Hackenberg, Board Member for Technical Development. "- An extreme driving machine for the motor sport enthusiasts among our customers, this car is designed for racing."
The engine in the Audi TT Quattro sport concept makes a
strong statement. The 2.0 TFSI has an output of 309 kW (420 hp) at 6,700
revolutions per minute - a new standard in the two-liter category. Its specific
power output is 155 kW (210 hp) per liter displacement - that's more than even
in 2001 Le Mans winning R18 race cars, which was the first time Audi combines turbo
charging with FSI direct fuel injection. The four-cylinder engine has 450 NM of
torque (331.90 pounds-ft) in the speed range 2400-6300 rpm. With over 300 NM
(221.27 pounds-ft) already at only 1,900 rpm.
With a curb weight of 1,344 kilograms ([2,963.01 lb] without
driver), the Audi TT Quattro sport concept is an athlete in top form. PS Each
of the two-liter TFSI that weighs itself is supplied less than 150 kilograms
(330.69 pounds), less than 3.2 kg shall (7.05 lb) to move. The four-cylinder
engine catapults the show car from 0 to 100 km / h (62.14 hours miles) in just
3.7 seconds.
Head of Power train Development Dr. Stefan crunch: "The
high-performance engine is an impressive demonstration of the power reserves in
our EA888 engine range This power supply has received numerous awards around
the world and she has been living his claim in many Audi sports models. In the Audi TT Quattro sport concept, its full potential, it demonstrates. The 35 years of
experience we have gained in the field of turbo charging this engine, the
unique combination of maximum power dynamics manifested, and fuel efficiency.
"
The powerful motor is back on the successful EA888
technologies such as the Audi valve lift system (AVS) variable valve timing,
dual-camshaft adjustment and dual-injection system (FSI plus MPI). A wide range
of modifications are presented, including special aluminum pistons with
integrated cooling channels and an ultra-high-strength forged steel crankshaft.
The cylinder head is cut a logical development of the higher loads and increased gas throughput. Accommodate the higher output is familiar, very compact thin-walled cylinder crankcase of the EA888 is here of a high strength casting alloy. The newly developed turbocharger has optimized mixed-flow technique and produces up to 1.8 bar boost pressure.
When driving, pronounced sporty character of the
four-cylinder is breathtaking. The turbocharged direct injection engine
responds instantly to the throttle and speed with voltage to the fuel cutoff at
7,200 revolutions per minute.
The 2.0 TFSI delivers its torque in a compact, three-shaft S
tonic. The dual clutch transmission gears in fractions of a second, adding its
share to an impressive acceleration of the show cars.
The Quattro permanent all-wheel drive delivers the power to
the road. An optimum weight distribution of the hydraulically actuated,
electronically controlled multi plate clutch on the rear axle. The Quattro drive
controls active distribution of torque between the axles in milliseconds, thus
adding to dynamic handling of the car. Also read the interesting article on Mercedes-Benz SL63 AMG 2013
