It’s official: diesel Panamera is coming

New oil-burning GT will be Porsche’s most fuel-efficient car ever. But would you want one?

It’s official: diesel Panamera is coming

Even if you're not a fan of the Panamera's questionable looks - and we're most definitely not - can you complain about a grand-touring Porsche that returns 43.5mpg? It will be the most fuel-efficient car in the manufacturer's history. And what concessions will we have to make for such thrift? Not many, actually.

See more pics of the diesel Panamera 

The twin-turbo 3.0-litre V6 diesel engine in Porsche's new Panamera produces impressively Porschey performance - 250bhp and 405lb ft of torque (36 more than the V8 petrol-powered S) - which gets it to 62mph in 6.8 seconds and a top speed of 150mph.
 
You'll be able to get 745 miles out of every 80-litre tank. That's 425 laps of the Top Gear test track. And if you spec lower rolling resistance tyres you get even more to the gallon - 44.8, to be precise. That's another few goes round Dunsfold right there.
 
The standard spec's not bad either. The £62,134 entry-level Panamera D - recognisable by slightly unbecoming ‘diesel' graphics on the door - gets leather seats, engine stop/start, a vehicle tracking security system and touch-screen satnav before you start ticking option boxes.
 
Don't expect it to grab you by the bits in the handling stakes. It's rear-wheel drive only and comes with the economy-biased eight-speed Tiptronic S gearbox. But if you want the real Porsche experience - and the 24.8mpg that goes with it - go buy a 911. This one, ideally.

We’ll reserve judgement until we’ve driven one. But if you can swallow the styling, cake and eating it do spring to mind for this correspondent...

Now share it...
