Breckland updates Beira V8-powered Kappa roadster

General Motors' Kappa platform has been widely praised for its performance characteristics (if also found somewhat lacking in ergonomics), so its choice as the basis of a custom V8-swap is in many ways unsurprising. It is, however, sure to be inspiring with a 400hp Corvette engine under the hood of the 3,100lb (1,400kg) roadster. Breckland's Beira V8, as the car is called, was revealed earlier this year, but now serial sales of the heavily modified sports car are beginning to get underway. A few changes to the car's design have been made in the interim, reports Sweden's Auto Motor & Sport, including an updated front fascia, with widened and more aggressive air scoops to feed cooling and power to the 6.0L LS2 engine under its hood. With its excellent power-to-weight ratio, the car's builders promise a 0-62mph (100km/h) sprint time of under 5 seconds and a top speed of 155mph (250km/h) - electronically limited, of course.
