BMW X3 vs Lexus RX Performance Specs
When you turn the BMW X3 on, you'll immediately hear the roar of the engine. That's German engineering for you. The X3 is powered by a 2.0L BMW TwinPower Turbo engine. This 4-cylinder engine delivers 248 horsepower, and brings together twin-scroll turbocharging capability with high-precision direct injection.
The Lexus RX 350 comes with a standard V6 engine that delivers 295 horsepower. You may get a bit more power out of this engine, but keep in mind that you're making a sacrifice when it comes to filling up. The Lexus RX only gets an EPA-estimated 20 city/27 highway MPG with the standard motor.
Compare that to the BMW X3, and it's truly no contest. This fuel-efficient crossover picks up an EPA-estimated 25 city/29 highway MPG with the entry-level turbocharged engine-well past what the RX 350 is capable of.
Of course, you may want that extra power. If that's the case, take a look at the X3 M40i trim, which comes with a 3.0L V6 engine that makes 382 horsepower. The RX has no way to compete with this.

Best of all, you don't have to look at your phone and away from the road when you're using Apple CarPlay™ or Android Auto (available in both vehicles). All you need to do is plug in the phone using the USB port, and its features and apps will appear right on the touchscreen in front of you.

Once you've finally settled on a song, you'll want to have a sound system that can keep up. The BMW X3 features a HiFi Sound System with a 205-watt digital amplifier and 12 speakers. The Lexus RX 350, meanwhile, only offers a 9-speaker system.
X3 vs RX 350 Comfort
With its available 14-way power front sport seats with lumbar support, the X3 is comfortable from the moment you leave the garage until the time you reach your destination. Inside the RX, you'll also find power front sport seats. Both Lexus and BMW take your comfort seriously.
It's worth noting, however, that comfort is elevated in the BMW X3 by the standard 3-zone automatic climate control system. The driver, front passenger, and those riding along in the second row can customize the temperature to their liking.
If you're driving the Lexus RX, you only have standard dual-zone climate control, leaving those in the second row to hope for the best.
