Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 25 - 76 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.
  • Older engines tend to be more expensive to run
  • New diesels promise cleaner CO 2emissions
  • Insurance is cheap though, as are servicing and parts

Vauxhall Insignia hatchback running costs are pretty impressive really. Insurance is very competitive for this type of car and Vauxhall parts and servicing tend to be good value for money.

The petrol engines are a concern when it comes to fuel economy and road tax though – they’re off the pace compared to similar models from other manufacturers. The diesels perform better, but still lag behind the standards set by other cars.

Engine updates in 2013 and 2015


As well as a pair of 2.0-litre diesel engines which are capable of a claimed 76.3mpg average fuel economy and CO2 emissions of 99g/km, a new 1.6-litre unit has been added.

This diesel unit produces 134bhp but just 99g/km of CO2 with 17-inch alloys and ultra-low rolling resistance tyres, plus economy of 74.3mpg.

Vauxhall Insignia emissions and fuel economy are only average yet Vauxhall likes to compare the Insignia to upmarket models like the BMW 3-Series. However, in this case, it’s not favourable. The 2.0-litre diesel BMW 318d returns 60mpg and emits 123g/km of CO2, while the Insignia 2.0 CDTi manages just 49mpg and puts out 154g/km of CO2. There’s no clever stop-start fuel saving models and disappointingly, some of the petrol engines emit slightly more CO2 than their predecessors in the Vectra.

Following the 2013 facelift things look far more positive – there are two versions with CO2 emissions of 99g/km which means far lower tax for both private and company car drivers.

Vauxhall Insignia reliability isn't likely to pose too many problems. Owners’ reviews from parkers.co.uk users show that the old Vectra is only average when it comes to reliability.

The Insignia is built to a higher standard and is expected to perform better, however this will only be borne out over time.

Recalls

There have been a couple of recalls over the Insignia’s lifespan, something that affects many manufacturers and models.

Steering wheel airbag may not deploy correctly

It has been identified that in the unlikely event of a collision, where there is a need for the deployment of the driver airbag, it is a possible that the drivers airbag module may separate form its mounting on the steering wheel horn plate.

Window anti-trap may malfunction

The anti-pinch or auto reverse function of the window regulator may not work correctly to ECE R21 requirements. So it is possible to trap items including fingers and limbs between the window and its closure.
