This here is the long wheelbase version of the all-new, fourth-generation Audi A8 that will debut at the this month's Beijing Motor Show in China with a new 6.3-liter W12 engine.
Ingolstadt's flagship limo has an overall length of 5,267 millimeters (17.28 ft), meaning it's 130 mm (0.43 ft) longer than the regular version. The wheelbase has grown by the same amount, to 3,122 mm (10.24 ft) while the height has increased by 2 mm (0.08 in) to 1,462 mm (4.8 ft). Width remains unchanged at 1,949 mm (6.39 ft).
All that extra length benefits rear-seat passengers who also get longer rear doors to further ease access.
