This new BMW M340d might be a curious collector’s item in decades to come. One of the last hurrahs for a meaty diesel engine in a sensible car, before the idea gets swept away in the electrification tsunami. What’s the spec of this Unicorn TDI?
You’d have to know your stuff to end up buying one of these. Hilariously, BMW will sell you a cheaper, less powerful 3 Series powered by a diesel straight-six: the 330d. It’s got 261bhp, 428lb ft and hauls to 62mph in 5.5 seconds. You don’t really need a faster junior exec than that, do you?
And yet, here it is. The M340d. The twin-stage turbocharged engine has been breathed on, and joined forces with a 48-volt starter-generator motor that adds 11bhp on its own and fills in any pesky turbo lag.
The result is 335bhp, and a staggering 700 Newtonmetres of torque. That’s 516lb ft in old money. Small wonder BMW has had to entrust drive to all four wheels, via a fettled eight-speed automatic gearbox. There’s even launch control, for heaven’s sake.
Could be a bit of a Q-car special, then?
I’ll say. Getting from 0-62mph in 4.8 seconds in any car is impressive! The way the M340d manages it is just silly though. It’s so fuss-free, you arrive at 62mph and it’s anti-climactic, as if the car’s just getting into its stride.
Underneath, this is a fantastically complicated machine. The engine is busy maintaining maximum boost pressure wherever you’ve got the throttle, it’s harvesting electrical energy and juggling the electro-surge, and the exhaust gases are on a magical mystery tour through a sewage treatment works-meets-waterslide, so this rampant runaway diesel locomotive actually complies with tougher tailpipe tests not actually coming into action until next year. And yet it’ll still keep a Cayman honest.
