Has the plug-in hybrid sporting executive saloon finally come of age?

The 5 Series cuts an unflustered figure. Given the old-shape car was already impressive in its all-round composure, and the new one has a longer wheelbase, wider tracks and, says BMW, even better weight distribution, this is hardly surprising.

In 550e guise, the new 5 Series also benefits from rear-wheel steering as part of the standard-fit, 5mm-lowered Adaptive Suspension Professional. This not only shaves half a metre off the turning circle but increases directional stability at higher speeds, when the hubs on both axles turn the same way. 

BMW’s PHEV-specific, stroke-dependent new damper control makes a difference. This is the best-riding 5 Series I’ve experienced, and it sets a new class benchmark.

When it comes to carrying speed, the 550e is mighty. The grip from its efficiency-minded Michelins is, if not outright superb, then more than good enough. However, it’s the quiet control of the chassis that leaves a lasting impression.

Mid-corner crests, crenellations in the road and unexpectedly tight bends elicit pitch and roll, sure, but these are deft movements, neatly cushioned at the variable extremities of the suspension’s travel (Sport mode is tightly controlled but leaves plenty of head room for the M5). Brake-pedal feel is also good, instilling confidence. It adds to the intuitive drivability of this 483bhp 5 Series.

However, you can’t ever quite escape the feeling you’re driving rather a large car – certainly one more so than before. The 5 Series no longer feels ‘right-sized’. In fact, many of the sensory cues during driving – the width of the bonnet, the well-managed but palpable heft of the body, the nicely weighted but manifestly ‘electric’ steering feel – are now more suggestive of 7 Series than 5.

The 550e is an accurate, assured and, when pushed, throttle-adjustable saloon, but all the chassis tuning in the world can’t disguise such size on the road.

You might expect the rear-drive 530e to be the purer driver's car, but in reality it feels like a slightly less rounded version of the 550e, at least without the Adaptive Suspension Professional. There's ample grip and body control, precise steering and subtle rear-drive balance, but not enough power to ever dent its composure

Comfort & Isolation

We've mentioned it a few times already in this review, but when it comes to ride comfort in the new 5 Series, the Adaptive Suspension Professional is absolutely pivotal. When we road tested the i5 40 on passive suspension, its rolling refinement was hamstrung by a reactive ride. It's a similar story for the 530e when not specified with upgraded suspension: although well-damped, the suspension is very firm and perpetually fidgety. It never really settles down, not even on the motorway.

On adaptive dampers, however, the 5 Series becomes a completely different proposition. For a car of its ilk, it provides wonderfully refined company both on the motorway and on more tortuous commuting routes alike, where it slips into EV mode whenever possible.

Its gait is fluid but never sickly in its movements, and the chassis’ isolation of vicious potholes and road-surface corrugations proved a thoroughly pleasant surprise, especially in light of those striking 20in rims.

Noise recordings of 66dBA at 70mph and 62dBA at 50mph are also excellent, and you can deduct 2dBA from each figure when in EV mode.

Less beloved by testers were the substantial A- and B-pillars, which inhibit visibility at junctions, and the fact that the bolster adjustment for the Comfort front seats is now accessed only via the touchscreen.

Track notes

Given the plug-in 5 Series’ mass and the scale of its new-found footprint, it would be tempting to chalk it up as a limousine with better than average handling and a good degree of pedigree feel – much like how we regard the 7 Series. However, when driven to its limits, the G60 5 Series reveals an additional layer of composure and dynamism beyond that of its bigger sibling.

Get the suspension loaded up and this is a five-metre saloon that will tighten its cornering line with a lifted throttle, and one in which the tail can be prompted to neatly arc around, then caught with ease using the accurate steering. This sort of ingrained poise bodes well for the upcoming M5, which will be no smaller than the 550e and, in all likelihood, will be heavier still.

Performance, of course, is more than adequate. Even on the steep Hill Route at Millbrook, this near-500bhp powertrain effectively stripped 500kg from the chassis.
