MTM's mental 312kW R8 killer

2009-11-20 10:17

There is no clue as to the 312kW worth of madness present here. MTM’s TT-RS, one indecently rapid little coupe.

Vehicle Specs
Manufacturer Audi
Engine 2.5l turbo
Power 312kW
Torque 560Nm
Transmission Six-speed manual
Zero To Hundred 4.2 sec
Top Speed 297km/h
When MTM Boss Roland Mayer showed off his 280kW TT-S in April, he promised the TT-RS version would be even wilder. Has he delivered?

Wettstetten-based tuner MTM has an enviable Audi product tuning portfolio.

After all, MTM boss Roland Mayer was one of the lead engineers on the original Quattro project during the early 1980s. He has an affinity for the brand, especially its five-cylinder performance products.

Five-cylinder turbo heritage

Tuning up the first five-cylinder production Audi with a serious performance bias in nearly two-decades (remember the RS2 Avant?) was something Mayer obviously did not take lightly.

MTM’s TT-RS simply had to be the business, not that the factory TT-RS is decidedly lacking.

The stock TT-RS 2.5l, direct-injection five-cylinder engine is boosted to 250kW and drives all four-wheels through a six-speed manual transmission – which is something of an oddity in a world seemingly obsessed with dual-clutch set-ups.

Looks very subtle, except for those 20-inch wheels. Performance increases are simply demonic...

Holistic upgrades - evil intent

MTM raises the performance bar thanks to customised intake and exhaust manifolds, reprogrammed ECU settings and a recalibrated turbocharger.  Mayer has managed to boost power up to 312kW, which is well into R8 territory.

Peak rotational force rounds off to 560Nm, which would mangle a stock Audi DSG transmission. Just as well the TT-RS runs that tri-pedal set-up straight from the factory.

To ensure the MTM TT-RS copes with such a strong increase in engine output (and velocity), the dynamic package is validated with 380mm brake rotors, actuated by eight-piston Brembo calipers.

Guaranteeing a surfeit of grip, Michelin Pilot Sport PS2 245/30 rubber rotates on multispoke MTM BIMOTO design 20-inch alloy wheels (with 20 or 30mm fore/aft spacing), whilst a re-angled rear-spoiler supplies additional downforce at speed.

Dual exhausts with individual throttle valves ensure that sonorous five-cylinder growl is as 1980s Quattro authentic as possible.

Porsche humbling performance

So, if you want R8 pace, yet prefer your Audi performance coupes a little more subtle looking, MTM’s TT-RS is a very neat compromise.

MTM says that on a good surface with judicious throttle-clutch coordination, you'll see 0-100km/h in 4.2 seconds and run through to a top end of 297km/h.

Just in case you doubt the engineering integrity and power claims of MTM, the company’s RS6 R estate ran an independently verified 344km/h during testing at Nardo in Italy.

If your brother-in-law runs a Porsche 911 Carrera 4 and you want to really test his tolerance for public embarrassment, the MTM TT-RS is just the ticket.
