Here’s full details of the new 2010 Devon GTX, what the company calls a true American supercar. But seriously, is it really worth paying US$500,000 for what people would think is a rebodied and more hardcore version of the Dodge Viper? It isn’t even going to be a limited edition, but Devon will be making 36 cars annually in southern California.

Basically the car gets a whole new look that still carries cues from the Viper, and its 8.4 litre V10 sounds exactly like the motor in the Viper, except it puts out 650 horsepower instead of the 600 in the Viper. Not a particularly high-revving engine either, with peak power coming out at 6,100rpm. Funky high-tech twin clutch gearbox? Nope, you get a 6-speed manual, which Devon says is track-proven.

Devon says the 8.4 litre V10 uses two valves per cylinder, variable valve timing, a coil-on-plug ignition system with “platinum tip spark plugs”, and more. I can’t really find much enthusiasm about the specs list after reading about the kinds of stuff that BMW does with their M engines. The company goes on to talk about the diameter of their exhaust tubing – exactly like how a tuner in Sunway would be recommending a custom aftermarket exhaust system spec to a potential customer.

Brakes are 380mm units from StopTech with 6-piston aluminum calipers at the front, and the car has an LSD. The wheels are either 18/19-inch or 19/20-inch lattice structured forged center-lock wheels wrapped with Michelin Pilot Sport Cup tyres, which are the best in the Michelin range.

The carbon fiber chassis (with a 98.8 inch wheelbase – the same as a Dodge Viper) will also feature a Continuously Variable Damping System which will not even be available at launch time. The system uses electronically-controlled variable damping forces to provide better response and tyre contact to road conditions.

The car also has an articulating front splitter (again, only available later and not at launch time), which travels approximately 80mm forwards or back via hydraulics to produce optimum downforce. The dampers can also be adjusted about 60mm up or down, which Devon claims is an “uncommon application”. The higher ride height is set to be softer while the lower setting are stiff.

Can’t wait to see how many pre-orders the company gets at the Pebble Beach event where it has been unveiled in person.

I stumbled upon this really nifty utility on the internet. Kouki Tech has this really cool Flash-based utility where you can easily compare different tyre and wheel sizes both through hard numbers (end result of circumference, diameter, sidewall height) as well as visually see how different the tyre sizes will be. It’s very useful if you want to change to a tyre size that’s different from your car’s original size. The utility will also tell you how off your speedometer reading will be.
