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.

Mercedes Benz SL55 AMG vs. Audi RS4
The SL500 was the top-selling version of the SL-Class early in the R230
series. It used a 5.0 L V8 engine, which produced 306 hp (228 kW) and 339
ft•lbf (460 N•m).
A 5.5 L 32-valve V8 engine replaced the 5.0 L found in the SL500 for 2007.
The engine is essentially the old SL55 engine without the addition of Supercharger. The 5.5 litre natrually
aspirated V8 can also be found in the new SLK 55 AMG. This model will
retain the SL500 name in most markets, but will be sold as the SL550 in
North America. It now produces 382 hp (285 kW) and 391 ft•lbf (530
N•m). It now accelerates from 0-60 mph in 5.3 seconds and has a limited
top speed of 155 mph (249 km/h).
In 2007, Mercedes will create 75 limited-edition 50th Anniversary SL550s.
According to another article, Mercedes created 550 of these cars, all
pewter in color with burgundy leather, black ash wood trim, 18-inch double
five-spoked wheels, and matching 50th Anniversary Edition luggage.
The SL600 is the highest-output version of the non-AMG SL-Class models. It
uses a V12 engine which produced 493 hp (368 kW) and 590 ft•lbf (800
N•m) from 2003 through 2006 and was uprated to 510 hp (380 kW) and 612
ft•lbf (830 N•m) for 2007. It accelerates from 0-60 mph in 4.7 seconds,
according to Mercedes-Benz. However Car and Driver achieved extremely
impressive acceleration test figures with 60 mph (97 km/h) achieved in just
3.6 seconds, 100 mph (160 km/h) in 8.6 seconds and a Quarter Mile run in
11.9 seconds at 120 mph (190 km/h).
The SL55 AMG version was released in 2002 with a supercharged 5.4 Liter,
5439 cc Mercedes-AMG V8 engine. This produced 493 hp (368 kW) at 6,100 rpm
and can propel the car to 60 mph (97 km/h) in 4.7 seconds, according to
Mercedes-Benz. Car and Driver got 60 and 100 mph (160 km/h) in 4.5 seconds
and 10.9 seconds, respectively. The car completed the Quarter Mile in 13
seconds flat at 110 mph (180 km/h).
The SL55 AMG was updated for 2007 with a 510 hp (380 kW), 531 ft•lbf (720
N•m) version of the same engine. With increased power and torque, the car
can now, according to the official website, accelerate to 60 mph (97 km/h)
in 4.4 seconds, 0.3 seconds quicker than before. The new model has only
slight visual differentiators, the most noticeable is the three-slat grille
rather than the four-slat version used previously. The top speed is limited
to 155 mph (249 km/h), but can be extended to 186 mph (299 km/h) for an
additional cost. The 6.3 liter V8 is expected to replace the current engine
for the 2009 model year. Upon release in 2002 this was for it's time the
fastest automatic car in the world. Of course this was before the SLR
Mclaren hit the market in 2003-present.
The SL65 AMG version offers 604 hp (450 kW) from its twin-turbocharged 6.0 liter, 5,980 cc V12 engine at
5500 rpm. It retailed for $179,720 as of 2005. Mercedes-Benz listed a 0-60
mph time of 4.2 seconds on their official website, though several road
tests show that it actually takes under 4 seconds to reach 60 mph (97
km/h). Car and Driver achieved 60 mph (97 km/h) from a standstill in 3.8
seconds, 100 mph (160 km/h) in 8.2 seconds and recorded a Quarter Mile-time
of 11.9 seconds at 123 mph (198 km/h).
The SL receives a face lift in 2008 featuring a new front end that evokes
the classic 300SL with a large grille featuring a prominent 3-pointed star
and twin "power domes" on the hood, the car also features new headlights
with an optional "Intelligent Light System" and a new speed sensitive
steering system. A more signifcant option will be the addition of a new
entry-level model, the SL280 with a 228 hp (170 kW) V6. Another
breakthrough for the facelift SL is a new 3.5 litre high-revving V6 with an
316 hp and 360Nm torque in the SL350, a improvement of 44 hp and 10Nm over
the outgoing model. Also the outgoing SL55 AMG will be replaced by the
newer M156 6.2 litre SL63 AMG. This has the new AMG developed 7-speed MCT
"Multi Clutch Technology" semi-automatic transmission. This uses a twin
clutch design, a first for Mercedes and AMG. It features a compact, wet
start-up clutch and double declutching. it's fitted with four drive modes:
"C" (Comfort), "S" (Sport), "S+" (Sport plus) and "M" (Manual) and boasts
100 millisecond shifts in "M" mode. The face lifted SL will be debuted at
the Geneva Auto Show.
