Comparison - BMW X4 xDrive35i 2017 - vs - BMW X3 xDrive 35i 2015

You might already know that sitting up high and having a commanding view of the road can be a great thing. So if you're looking for a luxury SUV that gives you that sense of security along with a sleek design and strong performance, the uniquely styled 2016 BMW X4 is an interesting alternative.
Mid way through last year the xDrive35i model was replaced by the more performance-oriented M40i model. For all 2017 models, wireless phone charging and a Wi-Fi hotspot are added to the options list, while the upgraded iDrive interface included with navigation has been updated. Finally, the steering wheel included in the optional M Sport package has a new design

Pros
Strong performance and good fuel economy from its two available engines
High-quality cabin looks and feels expensive
Comfortable ride quality despite its sporty nature
Responsive handling bettered only by pricier sport-tuned rivals
High-performance M40i trim level is a rarity for the segment.

Cons
Low rear seat reduces comfort relative to the X3 and most competitors
Small cargo area for a vehicle in this class
Rearward visibility is compromised by sloping roofline
Costs more than a similarly equipped X3 which offers more room inside
Some controls can be difficult to learn
Adaptive cruise control doesn't perform as well as those of rivals.
