The new Porsche Panamera Diesel goes on sale in the UK from August, offering a good compromise between performance, comfort and economy. It can go from the Lands End to the top of Scotland without refueling.

That could be a Top Gear challenge, see if it’s true! As for facts and figures, the Panamera Diesel’s 3.0-litre V6 engine makes 250 hp (184 kW) and maximum torque of 550 Nm. It is only available with rear-wheel drive and an eight-speed Tiptronic S ‘box, does 0 to 62 mph in 6.8 seconds, and a top speed of 150 mph.

In terms of fuel consumption it does 43.5mpg, which given its 80 liter tank, it should have a range of more than 745 miles. The car is also fairly clean with CO2 emissions of 172 g/km. With the optional lower rolling resistance tyres, efficiency improves further still, to 167 g/km and 44.8mpg on a Combined cycle.

And the most important figure of them all, price. Porsche Panamera Diesel has an MSRP of £62,134. For that you get lots of kits as standard, including leather interior, Porsche Active Suspension Management (PASM), Bi-Xenon headlights, front and rear ParkAssist, tyre pressure monitoring, automatic dimming rear view mirrors, Porsche Communication Management with touch-screen satellite navigation and audio controls, cruise control and a three year warranty. The Panamera also comes exclusively with the Porsche Vehicle Tracking System (VTS) and a complementary driving course at the Porsche Experience Centre, Silverstone.

So yes, at 62 grand it is a bit expensive. But considering what you receive it’s not bad value.

Through its proportions alone, the Panamera stands out clearly in its market segment: measuring 1931mm (76.0in) in width and 1418mm (55.8in) in height, the Panamera is both wider and lower than comparable four-door models. The unmistakable, sleek GT silhouette is created by an overall length of 4970mm (195.7in) and short, sporting overhangs front and rear. This new model can be recognised by the lettering ‘diesel’ on the front doors.
