Last Updated: 20 Mar 2017
Showcasing sharper, edgier styling is the Vauxhall Insignia Grand Sport, a swanky new name for the replacement of the company's large hatchback range. This time around there’ll be no traditional four-door saloon, but this chiselled new look will also appear later in 2017 on the replacement for the Vauxhall Insignia Sports Tourer estate, as well as the new Insignia Country Tourer, complete with a raised ride height and SUV-inspired styling.

Running costs

  • Improvements on most popular engines
  • Diesel is still the most economical
  • Avoid the 2.0-litre petrol if you're after economy

The Vauxhall Insignia Grand Sport has a keen eye on costs, with 3-10% improvements in fuel consumption for the biggest sellers – the 1.5-litre Turbo petrol and 1.6 Turbo D diesel.

You can aim for 47mpg for the former regardless of whether you pick the 140hp or 165hp output, while the most powerful 2.0-litre, 260hp petrol comes in with a behind-the-times 32.8mpg. Bear in mind this engine is available only with four-wheel drive and an automatic gearbox.

No surprises that the 1.6-litre diesel is the most efficient, with 70.6mpg boasted by the 110hp version (65.7mpg if you pick the 136hp) and even the larger 2.0-litre diesel tops all the petrol figures with 54.3mpg.
