The BMW E38 750i XL L7 came with a powerful engine option. Under the hood, a massive 5.4-litre V12 petrol engine powers the vehicle. It generates a massive 322 Bhp and 490 Nm of peak torque. The car can do 0-100 km/h in just 7 seconds but the top speed is restricted at 250 km/h due to safety reasons. It is a rear-wheel driven car and the long-wheelbase makes it an extremely fun-to-drive car. However, most owners preferred to stay in the rear compartment of the vehicle.

Dhirubhai Ambani also owned a few other luxury limousines including a Cadillac Fleetwood, which remains parked at the new house of the Ambani family. There were many other cars used by the founder of Reliance Industries and many of them remain parked at the Antila among many other exotic vehicles.
