Armin Schwarz Ice Drive Rally Training
Totally sideways from Ivalo in Finland, about 200 km north of the Polar
Circle at around minus 30 degrees Celsius Armin Schwarz is conducting his
annual winter training. For two weeks, he welcomes new groups of rally
enthusiasts every two days to share a few secrets about driving on ice and

The 24hrs of Audi R18 e-tron quattro Sebring Test - /SHAKEDOWN
After winning the Sebring 12hrs, Audi stayed over to conduct tests of their
new 2012 R18 e-tron quattro and ultra Le Mans racecars. Leo Parente and
/DRIVE were invited to observe and talk with the team. Watch the e-tron in
action, listen to the thoughts of Dr. Wolfgang Ullrich [Head of Audi
Sport], Ulrich Baretsky [Head of Engine Development] and Allan McNish [one
of the 2012 Sebring winning Audi racers]. And more.
MulsannesCorner.com has a ton of R18 details. Enjoy.

2014 BMW M5 Competition vs 2014 Mercedes-Benz E63 AMG S Model! - Head 2 Head Ep. 44
On this episode of Head 2 Head Jonny Lieberman is joined by Mike Shaffer
and two extremely potent hyper sedans, the 2014 BMW M5 Competition and the
2014 Mercedes-Benz E63 AMG S Model. Between the two of them, these two
mighty Germans produce 1152horsepower and 1092
pound-feet of torque. On paper. After a day of horsing around/testing
Shaffer and Lieberman grow suspicious of each twin-turbo V-8's actual output. So, they take them to
the Dyno gurus at K&N
engineering to learn what's what. The results very well may shock and amaze
you. However, the boys come to the conclusion that numbers are only exactly
that: only numbers, and numbers only matter so much. One true test of a
super sedan is how it handles a twisting stretch of tarmac. The other is
how much you yearn for the car after you've walked away from it. How much
the keys itch in your pocket. While the results are definitive, this Head 2
Head is much closer than most. Have a watch!
Head 2 Head appears every other Wednesday on the Motor Trend channel.

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.
