Strange
as Las Vegas is, it's not quite as strange as the Audi TT RS. With its
hairy turbocharged five-cylinder, unglamorous VW Golf roots, and
scorching performance, the TT RS has all of the right stuff to share the
stage with a fire-breathing bearded lady. But damn if it doesn't
entertain. While taking our first drive of the U.S.-spec TT RS in Sin
City, we discovered that this compact coupe has emerged from humble
origins to deliver sports car competence that we never thought was
possible.
The five-cylinder freak
The TT's core DNA is still intact with the RS -- a transverse-mounted engine, a front-drive-based all-wheel-drive system, and a nose-heavy weight distribution -- but one key hardware change is enough to completely adjust this TT's attitude. That change is an engine swap from a boosted four-cylinder to a turbocharged five-cylinder that pumps out 360 hp at 5500 rpm. To realize the ridiculous power density of 144 hp per liter, the iron block is fortified with a forged crankshaft, forged connecting rods, and cast aluminum pistons.

Such
big power from such a small engine typically results in an unhealthy
amount of lag followed by an unmanageable wallop of thrust. Yet the TT
RS exhibits neither of those traits. It boasts refinement and power
delivery on par with that of the esteemed 2.0T. Responsive, potent,
emotive, the TT RS is reaffirmation of the Volkswagen Group's expertise
and consistency when it comes to building turbocharged engines. The
2.5-liter produces 343 lb-ft of torque over a wide band from 1650-5400
rpm. You won't experience the punch that quickly off idle, when the
turbo needs more time to spool, but the car builds boost linearly and
accelerates much like a normally aspirated car.
Audi
claims a zero-to-60-mph time of 4.1 seconds on the way to a top speed
of 174 mph. Those numbers alone are enough to silence any errant "chick
car" comments slow-pitched from the driver's seat of an
automatic-transmission 3-series. The TT RS is anything but, not just
because of how quick it is, but how competent it is when driven hard. As
a reminder that is no ordinary TT, the spirited five-cylinder creates a
soundtrack that can't be ignored. The RS steps off the line with the
deep burble of a big rig and swells into a high-pitched hum with a
subtle vibrato. From inside the cabin, it's an air-raid siren building
into a wail. This is an enthusiast's car, through and through. While a
dual-clutch automatic and roadster version are available in Europe, U.S.
buyers can only have a six-speed-manual coupe. The overgrown aluminum
shift knob fills your palm and adds to the satisfaction found in
wonderfully short and crisp throws. The steering wheel is a sculpted,
flat-bottom piece that's even better than what you get in an R8.
Track Toy RS
To exercise the TT RS at its limits, we went to Spring Mountain Motorsport Country Club in Pahrump, Nevada, with more than four miles of pavement that can be coned into twenty-three different courses. Over a 1.5-mile course, our enthusiasm for the RS continued to build with every corner. Turn-in is immediate but the steering never feels so quick that it's artificial. Effort and progressivity are perfect and body roll is nearly eliminated. During continuous lapping, the brakes -- with four-piston, fixed calipers up front -- consistently scrubbed speed heading into each turn, and never hinted that they were tiring.

The
TT RS is nowhere near as forgiving as its most obvious competitor, the
Porsche Cayman R. In that car, you can commit all manners of driving
sins before the tires give up and scream for a better line or a slower
entry speed. That's not to say that the TT RS is slower, it simply
requires more experience, more skill, and more confidence to drive it
quickly around a track. While the window of handling neutrality is
smaller, the TT RS responds nicely to both throttle lift-off and
power-on requests to rotate the rear end and in power, braking, and
handling, it responds as a sports car should.
Back
on the road, the RS's steering displays a familiar Audi shortcoming. At
parking lot speeds, the power assist becomes far too aggressive and the
wheel becomes lighter than that in most minivans. But that's a problem
that disappears above 10 mph, when the steering takes on a lovely
weight. Thanks to the magnetorheological dampers, the ride quality
remains civilized even in light of the exceptional body control. As we
bomb towards Death Valley, our speeds creep into the triple digits and
we explore bursts toward 120 mph. Deactivating sport mode relaxes the
dampers and takes care of the side-to-side rocking induced by the wavy
desert road.
A TT unlike any other
To set itself apart from the rest of the TT range, the RS features a fixed rear wing, unique fascias, 19-inch rotor-style wheels, matte aluminum mirror caps, and the requisite RS badging. While the TT's distinct shape obscures the impact of some of the changes, the RS's appeal lies in the way it drives. For $57,725, Audi delivers a lusty engine, tenacious grip, sharp steering, and a snappy six-speed gearbox. As good as the TT RS is, Audi recognizes that this car will resonate with a subset of four-ring diehards. While the car will be built as both a 2012 and 2013 model, total production is expected to be less than 1000 cars. No matter how small the volume is, though, the RS builds new respect for a car that had fallen off our radar.
