Auto Express said:Powered by a 1.6-litre turbocharged four-cylinder engine, the new range-topper feeds a huge 178bhp through its front wheels. As a result, the boxy five-door launches from 0-60mph in eight seconds and goes on to a top speed of 140mph. To help cope with the extra power, the chassis has been extensively tuned on UK roads, while the steering has also been upgraded.
Set apart by bold new bumpers, the range-topper wears its VXR badges with pride. The finishing touch is a set of striking 17-inch alloys. Inside, there are figure-hugging Recaro seats with blue upholstery to match the exterior paintwork. In the rear, the hot model retains the practicality of standard Merivas thanks to Vauxhall's Flexspace seating layout. The VXR logo is seen on the gearlever, instruments and steering wheel, while standard kit is generous.
