Honda is only showing advanced engineering of their frame on the front. The fortwo is engineered with strengthening all over it's chassis. Front, rear, even the short wheel base is purposefully chosen to better absorb side impact. My favorite piece of engineering is the rear floor and engine compartment. The engine will intentionally deflect under the passenger compartmment, not into it! I also like the fact that there are crash boxes on the front and rear of the smart fortwo.
The upright design makes entry and exit comfortable for all ages and is more visible as well. It is taller than many of it's Mercedes Benz relatives!
