GTM says feedback from the public has led it to turbocharge the Honda Civic Type-R powerplant in its GTM 40TR (track and race) roadster. Now, the Ariel Atom and KTM X-Bow challenger will reportedly do the zero-to-60 hop in 3.5 seconds, compared with the previous incarnation's under four seconds. That's been achieved, they say, by boosting the 2.0-liter powerplant to 300 hp.

Increased Turbo Charged Power and new design for Sporty GTM40TR.

GTM's new anniversary car - the 40TR (Track and Race) will be boosted with the arrival of a more powerful 300bhp engine and improved exterior design. The niche vehicle manufacturer based in the Midlands is turbo charging the Honda 2 litre Type R powerplant by another 80bhp following public feedback.

Lloyd Taylor, General Manager of GTM Cars Ltd. said: "Potential and existing GTM customers made us aware of the requirements for a more powerful version of the 40TR so we have boosted the Honda engine to over 300bhp, making the ultra light racing car even faster but still superb value for money."

The revised powerplant is expected to reach 60mph in approximately 3.5 seconds and go on to a top speed of well over 150mph.

The 2-seater featuring an exposed aluminium super-structure will also gain a revised front nose cone and rear wing. The 40TR has been designed as a joint venture with another Midlands company, Stadco Engineering, and is expected to cost between £14,000 to £16,000.

The Coventry company has designed and is manufacturing the GTM 40TR for the racing track as well as a road legal version both of which will have the potential to run on biofuel. GTM is exploring the potential for a one-make race series linked to the Energy Efficient Motor-Sports initiative.

First drives will be available by mid May 2007.
