When test driving the new X7, the day began with the V8 version, which will be the X7 xDrive50i. I’m assuming V8 will be the bi-turbo 4.4-litre and that it will produce approximately 445-horsepower. With this engine, the X7 is quick. Throttle mashing is met with a swell of torque and a standard-for-all 8-speed automatic transmission that eagerly drops a few cogs before lift-off. The entry-level M40i will sport the twin-power 3.0-litre inline-6 and should be good for 355-horsepower. While not as powerful, it’s lighter constitution makes a huge difference in the driving dynamics department.
