MPG, running costs & CO2 Rating

4.0 out of 5

Cars are products that – in general terms – are hugely improved with every update. The Vauxhall Insignia is an excellent example of this upward trend. It’s lighter than the previous generation and its engines are more efficient, which means it’ll be cheap to run. It’s also, somehow, far less expensive to buy than the old Insignia, and undercuts rivals like the Passat and Superb by a considerable margin.

Vauxhall Insignia MPG & CO2

Company-car tax is likely to be the make-or-break point for the Insignia, as the vast majority of sales will go to fleet buyers; the news here is excellent.

Because tax obligations for company users are determined by the car’s price combined with its CO2 emissions, the Insignia’s low list price works in its favour. The Insignia engine with the lowest CO2 emissions – the 120bhp three-cylinder turbocharged 1.5-litre diesel - is capable of 61.4mpg while emitting 122-144g/km, making it a decent choice for company-car drivers thanks to a mid-range BiK rating. Every facelifted diesel Insignia is now RDE2 compliant, meaning they are exempt from the additional 4% Benefit-in-Kind (BiK) surcharge.

The Volkswagen Passat and Skoda Superb are available with standard petrol and diesel engines that occupy similar BiK brackets, with their respective plug-in hybrid models sitting in lower BiK bandings. However, both of these rivals' list prices are significantly higher than the Insignia’s, with the PHEV versions costing a third or more to buy at least.

Insignia buyers get a choice of two petrol engines and both are equipped with a nine-speed automatic gearbox. The 197bhp 2.0-litre petrol officially returns 33.1-37.7mpg, while the 227bhp version, which is reserved for the range-topping four-wheel drive GSi model, is almost as efficient, managing between 30.3mpg up to 35.3mpg. Emissions for the petrol engines range from 167g/km to 200g/km, placing them in the upper BiK bandings for company-car drivers.

An entry-level 143bhp 1.4-litre petrol is expected to join the line-up later this year and be capable of around 45mpg. A hybrid model is also expected to arrive, which is likely to borrow the 1.6-litre petrol engine and electric motor used in the Grandland X PHEV.

The diesel engine pairing offers far greater efficiency, with the entry-level 1.5-litre three-cylinder capable of 61.4mpg when equipped with a manual gearbox. Go for the automatic box, and economy falls to 56.5mpg. Emissions range from 121-145g/km for the manual, rising to 130-150g/km for the auto depending on the wheels and specification chosen.

According to Vauxhall, opting for the 2.0-litre four-cylinder diesel engine delivers identical fuel economy, with the manual capable of 61.4mpg, which falls to 56.5mpg when you opt for an auto. Emissions range from 121g/km for the most basic version with a manual gearbox, rising to 149g/km for a higher trim model with an automatic.

One word of warning: if the facelifted Insignia is like its predecessor, expect secondhand values to be somewhat unimpressive – although this won’t be of concern to company-car customers.

Every version of the Insignia will cost £150 a year in road tax, but if you go for the top of the range sporty GSi model, you’ll find yourself over the £40,000 barrier and liable for an additional £325 a year in VED.

Insurance group

The 1.5-litre entry-level diesel Insignia with 120bhp starts in group 17, while the 2.0-litre 172bhp version sits six places higher in group 23. The 197bhp petrol, meanwhile, starts from group 27, with the range-topping 227bhp GSi model placed in group 30.

Warranty

Vauxhall’s three-year/60,000-mile warranty is average and nowhere near as generous as the five-year guarantees offered by Hyundai and Toyota, nor the seven-year policy provided by Kia.

Servicing

The Insignia requires servicing every 20,000 miles or once a year, whichever comes first, and Vauxhall’s fixed-price servicing packages and maintenance jobs should make taking care of the Insignia an easy and reasonably affordable process. Vauxhall Care costs around £20 per month, including three services, three years of roadside assistance and the first MOT.
