New 3.0-litre V6 diesel for Porsche Panamera

According to Khabar Khodro, Porsche has updated the Panamera diesel by fitting it with a new version of the Audi-sourced 3.0-litre V6 turbocharged diesel engine, which will replace the current 247bhp motor.

To be unveiled at the Frankfurt Motor Show this month, Porsche is hoping the new engine will make the Panamera retain competitivness in a market that now features the all-new Mercedes S-Class and facelifted Audi A8..

Sharing only the same dimensions with the current V6 diesel, the re-engineered engine features a new crankshaft and pistons.

More impressive is that torque climbs by 100Nm, to 650Nm, meaning the Panamera sprints from 0-62mph eight-tenths faster than its predecessor. Top speed has also increased from 151mph to 161mph.

The suspension has also been retuned.

The new diesel returns 44.1mpg. Likewise, the power boost has caused CO2 emissions to increase, up from 16g/km to 169g/km of CO2.

The new 3.0-litre V6 diesel engine in the Panamera will be available from January 2014, with prices expected to rise a little from today's £62,922.
