I installed a Curt 110200 Class 1 hitch onto my 2015 ForTwo Electric Drive and figured I'd share my experience. I used this thread as a guide:
As well as this video:
The Electric Drive is slightly different, but in a good way. There's no belt cover to mess with, so I just omitted the use of the washers for it. The rest was about the same. Some tips:
- The bolt that you need to remove is an E20 female Torx socket. I think this might vary from year to year. It's a stiff bolt, so you probably don't want try and use something "close enough".
- Have a maybe foot-long, thin socket extension (3/8") to make torquing the Torx bolt easier...Otherwise you're likely to be going back and forth one click at a time with your socket.
- A good punch will be handy for preventing the drill bit from squirreling around. I had to use two bits to get through (smaller one first, larger one after).
- Make sure you have a tungsten carbide cutting bit. I used a standard bit with my Dremel and it did nothing. The carbide bit made it a 10-minute cut.
- The hole you embiggen needs to fit both the lug and the bolt that will pass through it, so have them both handy while you're cutting to check if the hole is big enough.
- Safety glasses and a comfortable position will be your friend as hot steel chips rain down upon thee from on high for minutes of drilling and cutting. Also headlamps are dope.
- I couldn't quite torque the front-most bolts to 70 ft-lb. I got them damn tight, but not quite there. The front lug kept spinning freely inside the frame, whereas the other lug hits the side of the frame, which prevents it from spinning.
- I had the car on stands by the factory jack points in front of the rear wheels. When I started removing the stock bolts, I noticed the whole subframe was coming down with the bolt...I wasn't sure if that was okay or not, but I didn't like it. I wound up supporting the car by the rear suspension (the big hollow swingarms) and that prevented the decoupling.
- It might be worth having some touch-up paint on hand to help prevent rust on the bit that got cut. Maybe just shoot some Fluid Film up there...
- The hitch is rated for 200 lb tongue weight and 2000 pound tow capacity, but the Smart is rated for zero
in the US. Tow light, tow slow.
