Currently reading: Revealed: New BMW M5 packs 717bhp hybrid V8

Flagship 5 Series goes PHEV and promises to be BMW’s most extreme yet. How’s it shaping up?

The reinvented BMW M5 is headed to UK dealers later this year with a thumping, 717bhp V8-engined plug-in hybrid powertrain and a starting price of £110,500.

The seventh-generation version of BMW's ’bahnstorming super-saloon makes the landmark switch from purepetrol power to an electrified system with total outputs of 717bhp and 738lb ft – far above those of any previous iteration.

That’s enough punch for 0-62mph in 3.5sec and a top speed of 189mph in derestricted Driver’s Package guise. The M5 uses a new high-revving (7200rpm), 577bhp twin-turbocharged 4.4-litre V8 and a 196bhp electric motor inside an eight-speed automatic gearbox, in a set-up familiar from the M division’s first PHEV, the XM SUV.

The M5’s outrageous pace comes in spite of a dramatic increase in bulk to around 2400kg. The chunky 18.6kWh drive battery (which provides 42-43 miles of electric-only range) contributes to an uplift of nearly 500kg over the previous, pure-V8 M5.

The M-fettled chassis – with the suspension, steering and structural components all uprated over the standard 5 Series – is equipped as standard with adaptive suspension, a bespoke M differential and a rear axle that can steer up to 1.5deg to boost manoeuvrability and stability.

The cabin is more familiar from the standard 5 Series, but there are bucket seats, lashings of carbonfibre trim and a bespoke control panel for adjusting the driving modes.

There are also physical controls for a raft of performance-focused functions, including a lap timer and launch control.

Order books are open now ahead of production beginning in November.

This will go the same way as the Mercedes-AMG C63S E-Performance... no one will by them because they're too heavy and too expensive. And this one has the added negative of being unattractive as well. The only plus is that it has a V8. Otherwise, this is BMW losing direction.

But the weight and the looks?!

I have a 10-reg E63 and it's a featherweight compared to this new M5. I used to have a 2300kg Bentley and it was no joy to hustle around public roads.

Across 2 generations of the M5, BMW has added a fair amount of weight to the car. The 4WD capability did a lot of value to the last generation but BMW seems to have failed with the packaging of the hybrid system in this new generation. I think that some other car brands would have stopped this sort of mistake with a redesign much sooner in the design and testing stages.

2400kg that's all you need to know about this. When a company loses all sight of what it was attempting to achieve.
