What is the difference between the BMW X7 XDrive and XDrive40i?

I am looking to purchase a BMW X7 and can't decide between the XDrive and XDrive40i models. Can someone explain the difference?

Hi Samantha, the main difference between the X7 XDrive and XDrive40i is the engine. The XDrive has a 3.0L inline 6-cylinder engine, while the XDrive40i has a 4.4L V8 engine. The XDrive40i offers more power and torque, but also has a higher price point.

Hey Samantha, another difference between the X7 XDrive and XDrive40i is the fuel economy. The XDrive40i has a slightly better fuel efficiency due to its smaller engine. However, the XDrive offers a smoother driving experience and more luxurious features.
