The General Motors micro car - which is sold both as a Vauxhall in the UK and an Opel for the rest of Europe - has been fitted with a 1.4-litre turbocharged four-cylinder engine with 110kW of power and 220Nm of torque, more than the next-size-up Barina RS warm hatch which uses the same engine (103kW/200Nm). The Adam's engine also features stop-start.
GM claims the Adam S has a top speed of 137 miles per hour - or 220km/h - and that the new flagship Adam model features VXR performance four-wheel disc brakes to help it pull up. Sports suspension and steering have also been included in the hot-hatch pack.
The Adam S gets a unique "Red 'n Roll" design theme, with red body paint and an anthracite grey roof, as well as 18-inch alloy wheels, a roof-top spoiler and lower body kit.
Inside, the Adam S gets Recaro sports seats, a leather-wrapped steering wheel, gear-knob and handbrake, and red and white interior trim finishes.
The Adam S is a "close to production" concept, which is expected to go on sale in Europe within months. It will be revealed at the 2014 Geneva motor show on Tuesday, alongside a new three-cylinder turbo Adam.
