Elfin Cars, the Australian boutique builder, will unveil a new-generation lightweight sports car in August. The car has not a name yet, but will have "electrifying performance and go-kart handling" with a power-to-weight ratio equivalent to a 630-horsepower Holden Commodore.

The new sports car will replace the Type-3 Clubman, a Lotus 7/Caterham-style Clubman that could be bought in a kit for home assembly.

Under the hood there will be Solstice's 2.0-liter four-cylinder engine that will deliver 260 hp.

The new Elfin will be priced under $60,000.
