Vauxhall Insignia BiTurbo
Price: £21,120-£33,320 Fuel: 42.2-57.6mpg CO2: 129-158g/km
Vauxhall has a split customer base for the Insignia, from the high volume end of the fleet market to the management-level user-chooser with its luxurious Elite, SRi and VX-Line trim levels. The BiTurbo diesel engine pitches for the latter, particularly BMW’s efficient, high-performance diesels.
Based on the familiar 2.0-litre CDTi engine this uses two turbochargers to offer lag-free performance throughout the rev range and 192bhp with 295lb.ft torque. But, by combining it with an eco mode, the BiTurbo is slightly more efficient than its less potent sibling – at a commendable 57.6mpg and 129g/km CO2. Figures most mass market manufacturers can’t match.
It makes the Insignia smooth and effortless in almost any gear. There’s a strong surge of power, starting just over 1,500rpm, which carries on almost to the redline making this flexible enough to hold in high gears to save fuel but with the ability to quickly overtake large vehicles as needed. Efficient “eco”, smooth “Tour” and responsive “Sport” driving modes mean it’s as simple to select a driving experience to suit the road conditions.
All BiTurbo models gain FlexRide adaptive damping, and there’s a choice of front or four wheel drive, automatic or manual gearboxes and hatchback or Sports Tourer estate on offer – all of which come under 160g/km CO2. Trimmed in leather and on the Insignia’s largest wheels, those switching from a luxury brand have only badge snobbery to overcome.
