They're starting to move away from the VW air cooled engines.
Un modified VW air cooled engines aren't very efficient. I had a 1600 cc 1971 Super Beetle that pumped out only 60 HP.
The 1800cc Toyota 1zz-FE engine, used in the Corolla and Matrix, produces 131 hp. Now, it has fuel injection, 4 valves per cylinder, and variable valve timing, but by their nature, air cooled engines HAVE to run fairly rich, or they overheat.
