While many cars today in these categories settle for four-cylinder petrol and diesel units, a selection can give you a meaner V6 engine under the bonnet, which sure to offer extra performance and greater strength in other areas including torque.
At the same time the V6 engine cars on the market can still provide a relatively practical level of efficiency and running costs. With all this in mind here is our pick of the best V6 engined cars on sale for 2013.
At the top of the Citroen C5 family car range is a Exclusive trim model with a 240bhp 3.0-litre HDi V6 diesel engine.
This makes the model, available as a five-door saloon or Tourer estate, the most powerful and quickest specification of all. The engine is connected to a six-speed automatic gearbox as the only transmission option.
In either bodystyle the V6-powered C5 can cover the 0-60mph sprint in 7.6 seconds, and the top speed is 151mph on the saloon or 1mph less with the Tourer.
In either bodystyle the V6 C5 also returns an average fuel economy of 39mpg and CO2 emissions are recorded at 189g/km.

The current version of Jaguar’s full-size luxury saloon is most efficient when equipped with the model’s 3.0-litre V6 diesel engine.
The Jaguar XJ offers two power outputs from its V6, either 271bhp or 335bhp, but the exact performance figures depends on whether you get the shorter or long wheelbase XJ. With both power outputs the diesel is connected to a eight-speed automatic transmission.
The lesser powerful V6 gives the XJ CO2 emissions of just 159g/km, or increased to 165g/km with the long wheelbase version. The 335bhp XJ uses a supercharged version of the V6 diesel, and although CO2 emissions are increased to 224g/km the extra power lets the saloon cover the 0-60mph in just 5.7 seconds.

This stylish two-door Japanese sports car wields a 3.7-litre V6 petrol engine, connected to a six-speed manual gearbox.
Whether in the coupe or softop roadster bodystyle, the 370Z has a limited top speed of 155mph, but the 0-60mph sprint time on the coupe version is 5.3 seconds, 0.2 ahead of the roadster. Evidently then the V6 engine here makes the 370Z a very sporty package, to go with the muscular profile and various interesting onboard gadgets.
There’s also a slight difference in running costs as well, the 370Z coupe averages 26.9mpg, compared to 25.2mpg for the roadster, and the coupe also emits 248g/km in CO2 next to 262g/km for the roadster.

Supercars down the years have been widely associated with massive V8, V10 or even V12 engines under the hood. These days however some of the more modern iterations from the most popular manufacturers have shifted to smaller turbo-charged units which, deliver greater efficiency but also improved performance at the same time.
One such example of this school of thought is the technical marvel that is the Nissan GT-R; the two-door coupe fits in a 3.8-litre V6 petrol unit which produces 542bhp.
Whilst that power output may look someway down compared to some of the GT-R’s most illustrious rivals, it can still deliver an amazing 0-60mph sprint time of just 2.7 seconds, one very few cars on sale today can match.
Also whilst inevitably with every supercar it isn’t the most efficient car to run, it won’t completely obliterate your credit card savings either as the GT-R returns 24mpg and emits a fairly respectable 275g/km in CO2.
