The new Vauxhall Insignia is available to order, with prices undercutting its predecessor by almost £4,000 on key fleet models.

Range line-up includes Design, SRi, Tech Line Nav and Elite Nav versions.

Available as a five-door Grand Sport hatch and Sports Tourer estate, with a Country Tourer estate coming soon, the range is priced from £17,115 OTR for the hatch with the new 1.5-litre Turbo. For Sports Tourer customers, prices start from £18,615 OTR for the entry-level estate model.

The engine line-up also includes two versions of the 1.6-litre diesel engine; a 108bhp version which is priced from £18,485 and brings 70.6mpg with CO2 emissions of 105g/km, and the 134bhp version, which starts at £18,985, returns 65.7mpg and emits 114g/km.

These are offered across a familiar trim line-up including Design, Design Nav, SRi, SRi Nav, SRi VX-Line Nav, Tech Line Nav and Elite Nav versions.
