The new smart is basically the old smart. There is a slightly different exterior and a modernised interior, but the power train is the same as at the predecessor.

What the new smart forfour and smart fortwo offers in detail, how they drive, how much space they offer and what the range and battery look like, I’ll show during my review while doing my test drive in the smart EQ forfour and smart EQ fortwo model year 2020.
