There are many new small engines coming on the market that can be useful. Also a new breed rear engined cars like the new Twingo. I suppose it shares technology with other cars soon to appear. No doubt this is a whole package subframe/engine/suspension that bolts in place with just 4 bolts. Judging the size it could easy made to use in a kitcar. Much cheaper and more related to daily use and less to noise and performance.
