For This is the most economical petrol-powered panamera, averaging almost 40mpg - and more if you specify the low-rolling-resistance tyres.
Against The list price is almost prohibitively high, while the car doesn't handle as well as a conventional-engined model and the engine sounds thrashy when you rev it. Not as economicasl as the diesel.
Impressive as this is in engineering terms, the sums just don't add up. The diesel-engined model is more economical and much cheaper.
The entry point into the Porsche Panamera range is the the V6 petrol version, which comes with sat-nav, a leather interior, parking sensors, alloys and cruise control.
Other versions cost a lot more, but don't have much more kit. The S has a 4.8-litre V8 engine, the 4S adds four-wheel drive and the semi-automatic gearbox, while the GTS adds more power, air suspension and a sports exhaust. The 493bhp Turbo and 542bhp Turbo S are the most expensive - cars in the range, and we wouldn't blame you if you couldn't resist them. However, we think the 3.0 diesel version makes most sense - it's fast, smooth, doesn't cost the earth to run and still drives like a Porsche should.p>
You can add all sorts of exotic extras. There's a button to make the exhaust louder, carbon-ceramic brakes, or a Sports Chrono Package that includes F1-style launch control. Also, Porsche takes all Panamera buyers to the Silverstone racetrack, where instructors show them how to get the best from their car.
