Fiat Avventura to launch on October 21

Mercedes AMG GT.

Lamborghini SUV concept.

Only the A8 gets the option of a night vision camera.

Great hi-fi in all cars, but Merc’s Burmester is best.

No panoramic or rear sunroof option on the 7-series.

730d’s straight-six diesel is super responsive, but loud.

Acres of space in the back of the 7-series and support is good, but seats are just a tad too firm in this company.

BMW i-Drive is the most detailed infotainment system.

Optional split rear cabin makes the A8 a strict four-seater. Bucket-like rear seats are very supportive.

S-class has the best seats overall, with the ideal balance of softness and support; no tray tables here though.

Run-flat tyres mean no spare wheel with the BMW.

A8’s seat massage function feels the most invigorating.

Rear passengers too get a daunting array of controls.

XJ may not have as much room as the rest, but it’s more than ample. Seat controls oddly spread around cabin.

Lumbar, massage controls accessible only via COMAND.

Adjustable shoulder support adds a whole lot of comfort.

Jag XJ just as enjoyable to drive as it is to be driven in.

Jag touchscreen is low-res and a bit slow to respond.

Few as they are, panel gaps are eyesores inside the XJ.

A8’s digi-analogue dials clear and yet informative.

Too much is optional on A8, including Matrix LED lamps.
