Vauxhall's stylish baby car has appeared in a more performance-oriented form at the Geneva Motor Show.

The Adam S uses the familiar 1.4-litre engine already seen in the standard Adam but here it comes in turbocharged form to release 148bhp and 162lb.ft of torque, significantly more than the current most powerful Adam model.

As with other sporty Vauxhall models the Adam S has chassis upgrades including bigger wheels and tyres, stiffened and lowered suspension and high specification brakes. It also wears eye-catching 18-inch alloy wheels and a subtle bodykit. On the inside there are a number of upgrades including red accents on the leather seats and dashboard.

Although currently a concept Vauxhall says it is near to production rather than being a vision for the distant future, so a showroom version could appear before the end of 2014.

Also on the Vauxhall stand at Geneva was an Adam powered by Vauxhall’s new 1.0-litre three cylinder unit, designed for high efficiency but also good performance and is powerful enough to appear in other Vauxhalls across the range.
