MTM Supercharged B7 Audi RS4 Clubsport! Launch, 8250 RPM, Crazy Insane sound!
Test drive of MTM's Amazing Supercharged B7 Audi RS4 Clubsport!
The MTM RS4 Clubsport. What praise can we possibly give to the regular RS4
that hasn't already been said? It's simply a phenomenal and highly-capable
4-door unlike anything else available. In stock form it's good enough to
lap the Nürburgring Nordschleife quicker than any other 4-door sports
sedan on the market. It's exceptionally luxurious and well equipped. It
also comes with the tried and proven all weather conquering quattro
driveline now with a rearward torque bias. It's not perfect to all people
though. And so where there's room for improvement MTM steps to the
The centerpiece of the MTM RS4 Clubsport package is the liquid-to-air
intercooled, Lysolm-type, belt driven Supercharger that resides directly underneath the
carbon fiber bulge on the hood and feeds the car with 0.45 bar (6.5 psi) of
fresh air. This cleverly designed package sits smack dab between the
cylinder heads within the "V" of Audi's 4.2 liter V8 and Boosts power levels to a very impressive 535
horsepower and 428
ft-lbs of torque. The engine internals and compression ratio remains 100%
stock. A special carbon fiber vent on the hood gives extra clearance to the
Supercharger and helps keep underhood
temperatures checked. The blower assembly completely replaces the stock
variable length intake manifold.
It's important to note that the RS4 Clubsport is still a prototype, meaning
it is quite clearly a work in progress. The final version will certainly be
finely finished and up to OEM standards and aesthetics, as with all MTM
vehicles. The particular Supercharger on
this press car has actually been adapted from a standard S4 application,
which is evident by the holes in the intake runner where an IDI fuel
injector would normally reside. This same system is available on the normal
S4 and can produce up to 503 horsepower.
Roland has set the development durability goal of 50,000 km for this
Clubsport RS4. This means he is not going to release the kit into
production until the test car reaches 50,000 trouble free kilometers on the
stock engine internals. Currently, the press car has seen roughly 15,000
km, so there is a ways to go. However, press cars tend to see slightly
more, ummm, "wear and tear" than the average car so one can rest assured
that it has been thoroughly tested and developed under all conditions. We
drove this car hard, and it ran well without a hiccup.
Development of MTM's Supercharger system
was far from easy. Three important factors contributed to the overall
difficulty of the project; size (component packaging), heat, and ease of
Audi has already used up nearly all available space by just fitting a V8
into the A4 chassis. They've shortened the engine length as much as
possible by using smaller than usual bore-to-bore spacing and fitting the
accessory/cam drive to the back of the engine. This didn't leave Roland
much real estate to work with on the front side.
A Supercharger setup works by turning an
air compressor (blower) mechanically with a belt and pulley system. The
extreme revving capability of the RS4 engine means the entire belt drive
system must be able to withstand high speed and high torque operation. At
full Boost, the Supercharger can require 50 or more horsepower from the engine
to spin itself, which must be transmitted through this belt. Considerable
effort went into designing the belt/drive assembly to fit into the small
space and function without slippage under all conditions.
The additional heat generated by this setup necessitated the carbon fiber
scoop which peeks menacingly from the hood area. MTM also concluded
intercooling was vital for safe and consistent power delivery. Trials
without intercooling showed that intake air temperatures would climb too
high, which in turn would decrease power output as the ECU pulls back
ignition timing to compensate. Higher temperatures also increase the
likelihood of engine knock, not something welcome to an owner when a
$30,000 RS4 engine is in stake. The water-to-air intercooling system taps
cleanly into the factory cooling system adding an additional heat exchanger
before passing through the Supercharger.
"Power is nothing without control". This cliché statement holds especially
true with MTM's RS4. Simply adding more power to a stock RS4 would result
in a less rounded vehicle, perhaps not as effective overall as what
originally rolled off the line at quattro GmbH. The remainder of the
modifications were therefore designed to make maximum use of the additional
power produced by the Supercharger.
Weight saving measures bring the curb weight of the Clubsport down to a
claimed 1660 kg (3650 lbs). This is about 350 lbs less than a US-spec RS4
even while counting larger brakes and additional safety features.

MTM Audi RS6 Clubsport V10 Biturbo 730 hp Powerslide Acceleration 0-60 3.3 sec Vmax 227 mph
A short clip of me driving MTM's amazing 730 hp Audi RS6 Clubsport. This
car does 0-60 mph in the low 3's, 0-125 mph in 11 seconds, 0-186 mph in 33
seconds (faster than Corvette ZR1)
and has a GPS confirmed top speed Vmax of 227 MPH (set at Nardo).
Unfortunately my time with this car was limited so I spent more time
enjoying the drive than filming it. As a result, the video isn't all that
great, SORRY! Needless to say, it's an amazing and very fast sedan.
Similarities with other vehicles, for example with the legendary Audi V8
DTM edition of the years 90 and 91 can not be excluded -- that seems to be
the message of the MTM RS6 Clubsport, which the Audi specialist and refiner
MTM from Wettstetten/Ingolstadt is bringing out now. With a Power/Weight
ratio of 2.65 Kg/PS, the sport interpretation of the RS6 stands far ahead
of the former winner series' car which brought with its four-wheel drive
tears in the eyes of the adversary.
Company director Roland Mayer also seems to succeed in this, holding the
record for station wagons (344,2 km/h) with the MTM RS6 R and presenting
the RS6 R to the on board competition supercars mostly from back view in
Nardo at the Highspeed event.
The aim is now, 350 km/h, where the MTM RS6 Clubsport has more power and
less weight than the others. The result: more than 730 HP, around 860 Nm of
torque and weight just under two tons. The 5.0 TFSI V10 Biturbo with 6-speed triptonic with DSP, after its
power increase in Wettstetten/Ingolstadt, accelerates from 0 to 100 km/h in
3.6 seconds and 200 km/h will be reached just after 11 seconds.
The ingredients for the "MTM RS6 Clubsport" project are clear: less weight
and much more power than the series' car. Besides the modification of the
ECU, the engineers from MTM have demonstrated technical finesse to achieve
more than 730 hp and 860 Nm of torque available at 2.750 U/min. In addition
to that, a MTM stainless steel Exhaust
system -- catalyst and rear silencer (4-pipes, each one 80 mm with throttle
valves in 2 pipes and control system), as well as other details and
modified high-rev gearing have been built-in. About suspensions, the RS6
Clubsport gets a MTM height adjustable suspension kit that allows a 10 to
45 mm lowering. Concerning the wheel set, the BIMOTO rims in 20" or 21" are
suggested with, for example, Michelin Pilot Sport PS2 Tyres in the size
305/30 ZR 21. The standard Carbon-Ceramic brakes, which Roland Mayer
approves, are left on the car but stronger air brake system pipes can also
be ordered on demand. Whoever wants to convert his RS6 into Clubsport is
highly recommended for the MTM high power brake system with 405 x 36 mm
disks and Brembo's monobloc callipers with 6 pistons. Last but not least,
MTM offers a changed front axle geometry, which, in addition to the above
mentioned suspension kit, assures a much better behavior in curves.
Back to the legendary DTM V8 race car which stood out, 20 years ago, more
for its driving sensations than its optic tuning. We find here also other
similarities. Modification of the bodywork with a carbon diffuser and a
discreet carbon front spoiler lip, which corresponds to the credo of MTM's
manager, Roland Mayer: we have to win, not with eye-catching spoilers, but
with best times, best speed. When the driver's door is open, we can see
that sportiness inside as well as on the driver and co-driver seats, has
replaced the comfort of the series' car. Especially demonstrative: the
roll-cage and no rear seats. On top of that, RECARO bucket seats and a
6-point safety harness, give the best driving position and best answer to
our purpose: to concentrate on the driving. This is what the MTM RS6
Clubsport is all about.
Well this year it will be the same at car meetings on high speed tracks: Do
not underestimate the Audi Limousine, which drives like a rocket. It was
344,2 km/h in 2009, the target for this year is 350 km/h.
Another similarity? It was almost exactly 20 years ago, that the Audi V8
DTM achieved a lot of success. And it is exactly 20 years ago that Roland
Mayer decided to found his company MTM - Motoren Technik Mayer.
