Which used Vauxhall Insignia hatchback should I buy?
The Insignia Grand Sport range kicks off with the Design trim. This includes auto lights, keyless entry and start, electric front and rear windows, air-con, cruise control, a 7.0in touchscreen infotainment system with DAB radio, Bluetooth connectivity, Apple CarPlay and Android Auto smartphone mirroring, as well as a multi-function steering wheel. We prefer Design Nav, because it gives you all the kit listed above but adds sat-nav and the ability to fully utilise the OnStar service.
Move up to SRi and you get 17in alloy wheels, front foglights, tinted rear windows, auto wipers, a spoiler, dual-zone climate control and rear USB sockets. SRi Nav is much like Design Nav in that it add sat-nav. SRi VX-Line gets bigger wheels (unless you have the 1.6 diesel), sportier bodystyling, a heated flat-bottom steering wheel, sat-nav and a 4.2in colour display in front of the driver.
Tech Line Nav models are the same as SRi Nav but look less sporty. Over SRi Nav, you get front and rear parking sensors and lumbar adjustment. It’s well worth considering if you want a few more luxuries.
Elite Nav gets LED headlights, front foglights, tinted rear windows, heated leather seats and a Bose stereo. It’s also the only trim that's available with the 2.0-litre turbo petrol.
The GSi version is the sportiest pick of the range, with Michelin Pilot Sport 4 tyres, 20in alloys, different driving modes, Brembo brakes and a GSi styling pack for the exterior. Unless you want the fastest Insignia Grand Sport, it’s not worth seeking out in our opinion.
The 138bhp 1.5-litre turbo petrol is the cheapest engine but it still promises reasonable pace. Even so, we’d be more tempted to pay a little extra for the more powerful version with 163bhp, because it’s in effect the same as the entry-level engine but with a little more power. It’s flexible despite its small size and there’s only a penalty in fuel economy. The 2.0-litre turbo petrol is only available in top Elite Nav trim and comes exclusively with an automatic gearbox and four-wheel drive. It’s an expensive and thirsty option, though.
On the diesel front, there is the entry-level 1.6-litre with 109bhp. While you might think it’ll struggle in a car as big as the Insignia Grand Sport, it’s actually a flexible thing that is just about quick enough. It’s the cheapest to run but may struggle if you regularly have a full car. For that reason, we’d suggest going for the more powerful version with 134bhp because it pulls well from low revs while sipping very little fuel.
The most powerful diesels come with the 2.0-litre engine in two states of tune: 168bhp and 207bhp. Performance is brisk (especially with the 207bhp version) but fuel economy figures are disappointing when compared with similarly potent rivals. Unless you’re towing something big, we’d avoid these and go for the 1.6 instead.
