Launch of the 2012 Mosler RaptorGTR : 649hp/ton : Serial #001 of 1         Highest power-to-weight ratio factory street car for 2012

Supercar Engineering, Inc.      Distributor for Mosler Automotive      10 October 2012

The financial downturn has produced numerous stories of great businesses and products getting caught in the vortex.  As the Director of Engineering for Mosler for over 7 years, we developed an extraordinary product with an immense quantity of technology focused on creating the best street-legal, track-capable hyperexotic in the world.  The primary differentiator in the Mosler product was extensive the use of the strongest and most expensive materials in the world.  For example, the roof structure was a total of 20 layers of 3×3 twill carbon-fiber yielding safety cell that proved to be the strongest structure the crash-testing agency had ever tested.   Pound-per-pound, carbon-fiber is 5 times stronger than steel.

The development and testing process for a vehicle at the cutting edge of technology is lengthy and extraordinarily expensive.  It’s the sport of kings.  In the case of the Mosler MT900s (the first Mosler vehicle), even if the truly massive development, crash-testing, emissions-testing, certification and tooling expenditures are ignored; the cost to build every Mosler vehicle exceeded the sales price.  This is the sport of kings, but in the big picture the product had enormous future potential given the broad-based racing success and the truly superlative product.   Earlier Mosler products won the Car & Driver Lightning Lap both times that it competed against the best from Lamborghini and Ferrari.  Mosler MT900R race cars hold the highest percentage of podiums/start of any manufacturer in FIA sports car racing.

The pinnacle of the Mosler’s street & racing development is the RaptorGTR, which combines the proven, crash-tested, ultralight, LeMans Prototype-style construction chassis with a truly exotic powerplant with visible twin turbos and several upgrades to the interior and exterior.  The combination produces 838hp at a dry weight of 2580lbs; netting a power-to-weight ratio of 649hp/ton.  The turbos behind the 7.0L forged V8 engine produce a fighter-jet soundtrack above 4000rpm that is unlike anything else on the road.

Acceleration = Force / Mass.  The RaptorGTR’s 838hp doesn’t sound superlative compared with the 1200hp Bugatti Veyron SuperSport, however horsepower is only half of the equation.  The other equally-critical factor is the weight that the engine has to propel.  The RaptorGTR’s 2580lbs (1173kg) is nearly a ton lighter than the 4545lb (2066kg)  Veyron SuperSport.   The Bugatti’s power-to-weight ratio comes in at 528hp/ton.  This is 121hp/ton less than the RaptorGTR.  For reference, a 2012 Porsche 911 has a power-to-weight ratio of 230hp/ton.

The chart below tabulates the power-to-weight ratio of the top supercars and hyperexotics available in 2012.

Product Power Weight Hp/Ton Price Production
Mosler RaptorGTR 838 2580 649 $700,000 1
Bugatti Veyron SuperSport 1200 4545 528 $2,400,000 100
Pagani Huara 730 2970 471 $1,200,000 100
Ferrari F12 730 3355 421 $450,000   (est) 3000
Lamborghini Aventator 403 3472 403 $425,000 4000

The hp/ton span from the Veyron SuperSport to the Aventator is 125hp/ton.  The jump from the Veyron SuperSport to the RaptorGTR is a similar 121hp/ton.  Ultralight LeMans-style carbon chassis/body construction is the key factor in creating the world’s highest power-to-weight ratio vehicle; even though the ultimate power is significantly lower than the 1200hp Bugatti.  Designed and built in USA….only one.

Only one person will get to enjoy the machine that Ezra Dyer of Automobile Magazine described as: “It’s like a bomb went off behind the rear bumper and we’re surfing the shockwave.”

The only place this vehicle will be shown is at the Epic Hotel, Miami on October 12-14thst, 2012 during the Festival of Speed.  See for more information.

Additionally, RaptorGTR #001 will appear Kat Deluna’s new “Wild Girl” music video in November.

Although only one person can own the highest power-to-weight ratio street car in the world, millions of enthusiasts will get to enjoy the online version of the RaptorGTR exclusively through; a new online racing community developed by the engineers behind the largest console racing games.  The virtual RaptorGTR is launching in November 2012 as the highest performing car in the game: 632 VPR.

The 2012  Mosler RaptorGTR was developed by Supercar Engineering and fully built by Mosler Automotive.  Supercar Engineering developed and owns technologies integrated into the RaptorGTR.

As an example of the depth of technology in the RaptorGTR is the rims.  The carbon-fiber rims (approximately 200 sets in the world) save 42lbs of Rotating Unsprung Mass compared to the lightest available forged aluminum rims.   Being 2x farther away from the center of rotation, the carbon weight savings in the rim has 22 = 4x the benefit (increasing acceleration rates and reducing braking distances) as weight savings from carbon brake rotors.   42lbs x 4 = 168lbs of equivalent RUM savings as compared to use of carbon brake rotors.  The typical set of carbon brake rotors save 20-30lbs of RUM.

Macroeconomic conditions, phase-in of electronic stability control requirements on low-volume vehicles built after September 1, 2011, and other looming regulations for the American market has led to the Mosler factory being idled after the first RaptorGTR was completed and sold to Supercar Engineering on August 25, 2011.  Supercar Engineering purchased the RaptorGTR from Mosler in conjunction with an Exclusive Distributorship in China and Thailand.  Since the change in circumstances has resulted in only one Raptor being built, SEI is marketing this unique vehicle to China as well as Russia, UAE, Saudi Arabia, and the United States.   The list price is $700,000USD, and interior and exterior can be tailored suit the buyer’s taste.  Please direct inquiries to Supercar Engineering, Inc: 203.668.3904 or  Supercar Engineering is responsible for the content of this release.  See for more information and photos.
