|The engine used in scooter trim|
The i3's range extender is a modified version of the 650cc Kymco engine used in the BMW C650 GT scooter. It's highly optimized for this particular use and puts out only 34 horsepower compared to 65hp when used for the scooter. It has a tiny 2.4 gallon gas tank which is positioned in the front of the car close to the filler door which is above the front right wheel. BMW claims the range extender will add up to 87 miles of range before needing to refuel but whenever a manufacturer says "up to" I've found you can easily discount that number by as much as 20% so without any proof I'm guessing it will provide around 70 miles of additional range.
|The range extender tailpipe is shown here. This picture was taken from the rear of the car and you can see how it won't be possible to see any tailpipe unless you bend over and look under the car.|
The Frankfurt Motor Show just opened a few days ago and Horatiu Boeriu, the managing editor for BMWblog was there covering the event. I have been providing content for BMWblog for a few years now and Horatiu usually asks me to cover electric mobility topics on his site. I asked him to get a picture of the underside of an i3 because I haven't seen any good pictures of that yet. I tried to get one myself at the i3 premier but the lighting was so bad my picture wasn't clear enough to use. So Horatui got the picture I asked for and I was pleasantly surprised to see the car he picked had the range extender option on it and he got a great picture of how BMW managed to conceal the range extender tailpipe so it's not visible from the outside unless you crawl under the car like Horatiu did to take the picture. This is important because many electric vehicle owners have expressed how they are proud they don't have a tailpipe on their EV. They don't want to see a tailpipe on their car, even if it's a range extended EV that happens to need a tailpipe. This is the very first picture I have ever seen of the range extender exhaust, and may just be the first one ever published.
