The petrol engine’s hum-drum torque peak of 155lb ft is developed at the same 4000rpm point as its peak power, and as you might expect it lacks the effortless shove of the 2.2-litre diesel. This wouldn’t matter too much if the petrol engine had a smooth delivery, but use plenty of revs and it betrays its presence with a gruff, harsh note that sounds more than a little laboured.
Neither is it any firebrand in terms of performance, and predictably you have to use plenty of revs to really get it moving. Fine – save the sound effects – but it’s hard to see it being possible to match the superb on-paper combined fuel economy figure of 47.9mpg when driven in such a manner.
If the lighter petrol 6 has the edge in driving manners over the diesel model then it’s not easy to detect based on this brief initial drive. Some of that is due to the disappointing steering on what is billed as a sporty car, which is always light and lacks incisiveness around the straight ahead. The ride is firm, with fairly aggressive rebound damping over larger intrusions, but the gearshift is a real joy, offering a tight, snappy change.
Should I buy one?
The new 6 Tourer is an attractively styled estate car with a practical cabin of decent quality, attractive design in most parts and impressive specification, but it is less rewarding to drive than we hoped.
And while those who insist on petrol power will naturally gravitate towards this model, it makes far more sense to opt for diesel power.
