Specifically, Krueger told Frankfurter Allgemeine Sonntagszeitung (as reported by Automotive News) that there was certainly room in the middle of the i sub-brand's current two-model lineup "from the number point of view." The exec declined to offer any additional information. Unlike the i3 and i8, which are their own unique products independent of the rest of the BMW range, the i5 will allegedly be based on 5 Series sedan. It would also eschew the all-electric approach of the i3 in favor of a new and different version of the plug-in hybrid powertrain used in the i8.
Rather than that car's turbocharged, three-cylinder gas engine, 129-horsepower electric motor, and 357 total system hp, the rumored i5 – according to our most recent report – would be significantly more powerful. There are rumblings that the new model would have anywhere from 544 hp to 640 hp, with at least two electric motors (one on each axle, making it effectively all-wheel drive).
On top of the high performance, the i5 will have no issue running on EV power. According to one report, there'd be up to 78 miles of electric range, and would run purely on electricity up to 36 miles per hour. Even then, the gas engine would only join the party when under hard throttle. What do you think? Will BMW come out with a four-door PHV that could potentially outrun the current M5?
