You start the engine by turning a glitzy toggle by the gearstick and engage drive from the eight-speed automatic box. There are no steering wheel-mounted paddles to change the cogs. As you accelerate away, the D5’s extra pace and traction compared with the D4 are immediately evident, not least because the turbocharged 2.0-litre has a little party piece to get things moving, named PowerPulse.
It’s a clever system invented by two young Volvo engineers and uses an electrically driven compressor to blast pressurised air into the exhaust manifold when the driver accelerates. It helps to spool up the first turbo before the exhaust gases join in, counteracting turbo lag and resulting in an impressively rapid and linear response. PowerPulse is currently available as standard on the all-wheel-drive D5 only.
Although driver engagement isn’t necessarily this estate’s raison d’être, it’s not exactly lacking, thanks to that surfeit of power. All V90s get three driving modes: Dynamic, Comfort and Eco. As with some similar set-ups, engaging Dynamic mode spices up the responses of the suspension, steering and throttle. And as with some similar set-ups, it isn’t completely successful: as well as quickening the steering’s responses, it incorporates some additional resistance that feels rather artificial. The Comfort setting seems perfectly adequate for this V90 in most situations.
Our test car was fitted with the standard suspension rather than the optional (£950) self-levelling air springs at the rear. A back-to-back comparison of the suspensions on cars both riding on 18in alloy wheels suggested that the standard set-up creates more patter and noise over rough surfaces and invokes a touch more body roll during cornering, but not to the extent that it detracts from the V90’s capability as a comfortable cruiser.
The V90 features clever technology aimed at making its occupants’ lives safer and more comfortable. They’ve seemingly thought of everything, even a system for reacting to large animals that may have strayed onto the road, as well as a raft of tech to mitigate an accident and damage to occupants should one occur.
We weren’t altogether convinced by the semi-autonomous Pilot Assist system on the car we tried. It offers assisted driving on motorways by combining active cruise control with lane keeping assist at speeds of up to 80mph, reducing driver effort and stress in heavy traffic.
The system has merit, but in our test car, it had a habit of tracking much more closely along the nearside white line, rather than being centred in the lane. If you’re in the middle of a busy motorway, it can feel like the system is guiding you unnervingly close to the adjacent vehicle on the left. Perhaps Britain’s ragged road surfaces and lane markings do not reflect the system to the best of its abilities.
