Crossfire coupe and upcoming roadster, dubbed the SRT-6, Startech has unveiled its own tuned Startech Coupe V8 6.1 hotrod at the L.A. Auto Show (first shown at Frankfurt's IAA in September).

Not willing to "make do" with a mere V6, the Startech team has squeezed an expanded displacement 6.1-L Mercedes-Benz V8 into the "Starfire," producing 426-hp at 5,400 rpm and 458 lb-ft of torque at 4,600. It's quick to 100 km/h at 4.7 seconds (60 mph in 4.6), before speeding to a top speed of 299 km/h (186 mph). All the power goes down to the rear wheels via a 5-speed automatic transmission with AutoStick manual mode and a custom-developed locking differential.

The Crossfire is already a stunning handler, but due to the additional stress on all systems Startech has fitted gas-pressure shocks, progressive-rate springs and stronger sport sway bars. The sport suspension

upgrade has been calibrated to compensate for the 8-cylinder engine's greater weight. Despite the racier specs, Startech states its suspension is comfortable for everyday driving.

Rounding out the handling package are exclusive one-piece Startech Monostar IV 8.5Jx19 five-spoke wheels on Pirelli 235/35 ZR 19 performance tires in front and 9Jx20 rims wrapped in 255/30 ZR 20s at the back.

Startech paid attention to the brakes too, upping the standard 4-wheel disc ABS system to larger diameter 355 mm vented and cross-drilled discs up front and 300 mm in the rear, with six- and four-piston fixed calipers respectively.
