The halo of the two new models is the Overfinch Sport GTS-X, which Overfinch describes as the most powerful, high performance Range Rover Sport in its stable. To reach that claim, Overfinch has remapped the ECU on the supercharged 5.0-liter V-8 and upgraded induction, boosting output to 575 hp - 65 hp over Land Rover's own "most powerful, high performance Range Rover Sport ever created." In order to send that message to the world around, Overfinch adds the grumble of a driver-controlled valve release exhaust system. Overfinch claims that the GTS-X has a top speed of 145 mph (233 km/h), a 5 mph (8 km/h) increase over the Range Rover Sport Supercharged HSE.
The GTS-X gets a few other enhancements, including a roof spoiler, upgraded Brembo brakes and an electronic lowering system. It rides on 22-inch forged alloy wheels.
To the eye, the GTS-X is defined by its copper-and-black color scheme. Outside, the copper body is accented by gloss black vents and two-tone Overfinch lettering on the tailgate and hood. The color scheme continues inside, where the Nappa leather interior is outlined in orange contrast stitching. The instrument panel is black with orange lettering. Carbon tread plates and a GT steering wheel with carbon inserts help complete the package.
Overfinch revealed the GTS-X at the Goodwood Festival of Speed earlier this summer. It will next show the car at London's Salon Privé, which begins on September 5. The model will be joined again by the Range Rover Evoque 2012 GTS - the bright, loud "ultra violet" SUV pictured above. That model has a cowhide-like combination of Lotus White leather interior and piano black veneers and contrasts. It sits on 22-inch diamond-turned black alloy wheels.
The GTS-X has a retail price of £147,500 (approx. US$231,500) and the Evoque 2012 GTS costs £89,995 (approx. $141,000). Buyers of both models can further customize their SUVs using Overfinch's suite of options.
