The Mosler MT900S is the road going version
of the mighty MT900 racer. This extremely successful
GT racer has been heavily raced in both America
and Europe and the resulting development has provided
the basis for the road variant, the MT900S. This
car is being produced in limited numbers in order
to homologate the racecar for Le Mans in 2007.
"The Mosler MT900S road car was designed
to be the extreme performance vehicle. In third-party
testing it officially set nine performance records,
including 0-60mph in 3.1 seconds," says creator
Warren Mosler. "Now that it has passed its
testing phase with flying colours, delivery can
begin in very limited numbers to a discriminating
coterie of racers, collectors, and investors."
The core of the ultra-high-strength, lightweight
Mosler MT900S is its advanced composite monocoque.
Assembled from carbon fibre and carbon-aluminium
honeycomb structural board this monocoque utilises
much of the composite technology generally associated
with Formula 1 and the aircraft industry. Substantial
carbon fibre sills and central spar structures
incorporated with the structural carbon front and
rear bulkhead, roof and A posts create this ultra-strong
and ultra light cockpit environment.
Providing location for the steering, suspension,
engine and transaxle are two chrome-molybdenum
steel subframes mounting directly to the structural
carbon bulkheads of the monocoque. The smaller
of the two subframes mounts transversely to the
front bulkhead and provides the strong points for
the front suspension wishbones and steering rack.
The more substantial rear frame runs longitudinally
with the car and provides the location for both
engine and transaxle as well as the rear suspension.
The mid placed Corvette LS6 V8 provides the power
for this stunning road and track capable supercar.
Available in up to 7 litres with 540 bhp/ 540lbft
the performance is exceptional. This power is transmitted
to the road via an inverted Porsche GT3 R 6 speed
manual transaxle and limited slip differential
although sequential shift race Hewland transaxles
are available to harness the power and torque should
the car be more track focussed.
The suspension is double wishbone at each corner
with damping control being supplied by Penske 3
way adjustable coil over units combined with adjustable
front and rear anti-roll bars. Aluminium uprights
from the well proven Corvette locate the hubs and
wheel assemblies. Steering is manual and the car
is available in both right and left hand drive.
As standard for the US market the car is fitted
with Corvette brakes for ease of servicing. For
European use the brakes have been upgraded to 355mm
diameter grooved and drilled ventilated floating
disc brakes with 6 piston Wilwood alloy callipers
front and rear to provide massive stopping power.
The MT900S rides on OZ Superleggera III 19 inch
front and 20 inch rear forged alloy 3-piece wheels
fitted with Dunlop SP9000 Sport tyres, Michelin's
superb PS2 high performance tyres are available
as an optional extra to further enhance performance.
The aluminium engine coolant radiator is situated
at the front of the car and is mounted on the carbon
fibre undertray. Fully ducted in carbon fibre and
mounted to the front subframe the front splitter
structure provides the initial crash protection
for any frontal impacts.
The rear body section provides the cover for the
engine and transaxle and gives location for the
adjustable carbon fibre rear wing. This rear body
panel can be raised for access to the ample luggage
space which can carry a pair of overnight bags
together with a set of golf clubs.
Final assembly of the car's chassis, body, internals,
suspension, and power train is completed by a team
of road car specialists at Breckland Technology
Ltd based in Norfolk, England. There, it is transformed
into a stunning example of cutting-edge automotive
technology and beauty, accentuated by its low-slung,
flowing lines and 19 inch and 20 inch aluminium
wheels fitted with four-wheel vented 14 inch disc
brakes. The MT900S is being developed, engineered
and assembled in close collaboration with Mosler
Automotive and the Mosler race teams.
The strength and capability of this car has been
recently confirmed when Mosler Automotive announced
that the Mosler MT900S supercar had successfully
completed U.S. emissions and Federal crash testing,
including California Air Resources Board (CARB)
certification making it fully compliant for sale
as a road legal car in America. The car is fully
SVA compliant in the UK and is now available built
to your specification for road and track use.
The Mosler is an extremely tractable car which
could be comfortably driven to Spa, tracked all
day and then driven home. The modular approach
from Mosler when designing their cars makes for
a very practical supercar. The carbon monocoque
with front and rear subframes and then front and
rear body sections allows for straight forward
repair of all but the most serious crash damage.
The diagnostic software is GM based and readily
available and suspension, shock absorber and anti-roll
bar settings are all fully adjustable to allow
absolute setup. This solid practical design approach
combined with the robust engine and drive train
allows for all the GT benefits but without many
of the supercar weaknesses.
Racing versions of the Mosler MT900 have been
making their mark for several years, winning both
the 2003 British GT and 2004 Spanish GT championships,
and competing successfully in FIA GT championship
races. Currently several international teams from
England and Spain are battling for championships
with the leading Ferraris, Porsches, and other
At the mid-May RAC Tourist Trophy race at Silverstone,
England, three separate Mosler entries shared the
starting grid for the first time and finished second,
fifth, and twelfth respectively and followed that
with another class win at the FIA GT race in Imola,
Italy. When eligible to race in the U.S. Grand
Am series, MT900s won numerous US races, including
the Rolex 24 Hours of Daytona in the GTS class.
