I had a Grand Tourer as a courtesy car a couple of weeks ago and it was rubbish. It was underpowered with the 1.5 petrol engine, with the same hp as an engine that I have used in a 1 series before and that was fine, as the car is so heavy. It didn’t like going around corners, and inside everything felt like it was in the wrong place and that you were perched up high rather than sat in. The only thing I liked was the leather lower dash.
The engine I had was branded as the 218i this is the same engine with the same output as the 116i, with the 116i being lighter and rwd the car felt loads faster.
Obviously the higher centre of gravity that a people carrier brings means that they don’t go round corners quite as well as a normal car. However from memory my old C-Max cornered better.
In my 3 series and the 1 series I previously drove the whole dash feels well laid out, everything is in a sensible place that you can reach without even thinking about it. I had the seat in the lowest position and it still felt really high, like I was sat on a stool, I think a lower driving position would have made the controls feel more natural and less of a stretch to reach buttons.
Edit
Just looked more into it as I didn’t realise that the 116i has now been changed to the 118i and a 1.5 3 pot. The old 116i with a 136bhp 1.6 4 pot was fine and even quite fun, god knows what the 1.5 will be like in it. Interestingly they have moved the old 118i to be the 120i but with the 1.6 4 pot and 177bhp.
