Unlike most large executive cars, you don’t get a plethora of four, six and even eight-cylinder engines to choose from in the Volvo. All S90s come with 2.0-litre, four-cylinder engines.

If you do a mix of town and motorway driving, the D4 is your best bet. It’s punchy enough to overtake slow-moving traffic (it’ll accelerate from 0-62mph in 8.2 seconds), reasonably quiet at speed and returns a claimed 61mpg – although you’re more likely to achieve around 44mpg in real-world conditions.

There’s also a D5 model with 235hp that comes with four-wheel drive as standard but it’s more expensive to buy and costs more to run than the D4.

If you fancy a petrol model, there’s a T4 with exactly the same 190hp as the D4, but it’s slightly slower to reach 62mph from rest than the diesel and only returns a claimed 42mpg. It’s still worth considering if you do lots of city driving, however.

If it’s a sporty saloon you’re after, you should consider the T5 models. It comes with 250hp and will sprint from 0-62mph in 6.8 seconds but it never feels that fast. It needs a bit of revs to get going as well, which is the result of it only being a 2.0-litre, but it’s a similar story in alternatives with equivalent engines. Ultimately, the T5 feels a bit out of place – you’re better off with one of the diesels. 

Whichever model you pick, your S90 gets an eight-speed automatic gearbox as standard. It changes gear nice and smoothly, especially at slow speeds, but doesn’t respond particularly quickly when you put your foot down. As a result, the Volvo doesn’t feel quite as rapid as the likes of a comparable 5 Series or E-Class.

It might be a big car, but you won’t have any trouble seeing out of the Volvo. The relatively thin pillars and large windows give you a good view out, and the light steering helps make it reasonably easy to manoeuvre around town.

If the thought of parking a big saloon car gives you chills, you can get the S90 with a self-parking feature that’ll steer you automatically into parallel and bay parking spaces that are just 1.2 metres longer than the car. This costs a decent amount extra but comes with a 360-degree camera system and a panoramic glass sunroof.

Thankfully, Volvo’s Pilot Assist feature won’t cost you a penny extra. This system combines lane-keeping assist with adaptive cruise control to accelerate, brake and steer for you at speeds up to 80mph – providing you keep your hands on the steering wheel. This helps make long journeys – especially on busy motorways – as relaxing as possible.

Adding to the S90’s stress-free driving experience is the comfortable suspension. It can get a little bumpy over the worst stretches of road in town, but at speed on the motorway, the S90 wafts along beautifully. R Design models get lower, stiffer sports suspension, which seems wrong in a car like this. 

Sadly, while the Volvo does a great job isolating you from the patchy road surfaces, it doesn’t feel particularly fun to drive. Sure, it doesn’t lean much in tight corners, but a BMW 5 Series and Jaguar XF both feel more involving on a twisty backroad.

If safety, rather than sportiness, is your main concern, the Volvo claws back plenty of points. It comes as standard with a wealth of active systems designed to prevent crashes including pedestrian, cyclist and large animal detection, automatic emergency braking and even a feature that’ll tighten your seatbelt if the car detects a possible collision.

All these features helped the S90 achieve an impressive five-star safety rating from Euro NCAP when it was tested in 2017.
