Signum beefed up

The range has no VXR model, but bosses claim the new 250bhp 2.8-litre V6 turbo should do nicely.

The car covers 0-60mph in 6.8 seconds and is limited to 155mph. It gets sat-nav, 17-inch alloys and electric front and rear windows as standard. The Signum range starts from £18,150 for the 1.8-litre Exclusiv.
