Vauxhall Insignia Grand Sport (2017-2021) Pros and Cons

Pros	Cons
Keenly priced on the used market	Not at all sporty to drive
Economical diesels are ideal for motorway driving	The Country Tourer isn't necessarily four-wheel drive
Well equipped whichever model you choose	A Skoda Superb is much more spacious

Quick Summary

The Vauxhall Insignia Grand Sport (2017-2021) is a D-segment saloon that competes with the Ford Mondeo and Volkswagen Passat. Despite its saloon appearance, it's actually a five-door hatchback with a full opening tailgate. Available as a Grand Sport hatchback, Sports Tourer estate, or Country Tourer with extra cladding, it offers a massive range of options. The Grand Sport provides 490 litres of boot space, expanding to 1,450 litres with the rear seats folded, whilst the estate variants offer even greater practicality for families and business users.

Engine options range from a 1.6-litre diesel with 109bhp to a potent 207bhp twin-turbo diesel in the GSi model. The standout engine is the 1.5-litre petrol with 163bhp, offering excellent performance, low-down torque, and reasonable fuel consumption. Diesels achieve around 55mpg in real-world driving, whilst the petrol manages approximately 45mpg. All models except the 2.0-litre diesels feature timing chains, reducing maintenance costs. Well-equipped across the range with dual-zone climate control, cruise control, and parking sensors on most trims, the Insignia Grand Sport represents exceptional value as a used purchase, though it lacks the sportiness of dedicated driver's cars and the spaciousness of the Skoda Superb.

Best for: Budget-conscious buyers seeking a spacious, well-equipped family saloon or estate; company car users; those prioritising motorway comfort and economical diesel engines.

Not ideal for: Drivers seeking a sporty, engaging driving experience; buyers requiring maximum interior space; those wanting premium badge appeal or cutting-edge technology.


Comparison vs Key Rivals



The Verdict

You should buy the Insignia Grand Sport if: You're seeking a keenly priced, spacious, and well-equipped family saloon or estate; you prioritise motorway comfort and economical diesel engines; or you want excellent value as a used purchase.

Consider alternatives if: You desire a sporty, engaging driving experience, maximum interior space, or premium badge appeal and cutting-edge technology.

Competitive Position: The Vauxhall Insignia Grand Sport is a solid, sensible, and dependable family choice that delivers excellent value for money on the used market. Whilst it won't excite enthusiasts with its driving dynamics or match the Skoda Superb's spaciousness, its keen pricing, economical engines, and comprehensive equipment make it absolutely worthy of consideration alongside the Ford Mondeo and Volkswagen Passat. Savage depreciation in this segment means used examples represent outstanding bargains, though the Skoda Superb remains the class leader in most areas.
