The trend is on to use electrical hybrid systems to boost the HP of conventional gas units. Lexus will soon announce: "300bhp 3.5-litre V6 mated to a 170bhp electric motor. Offering an astounding 470bhp, the car will feature all-wheel drive and be capable of around 60mpg. But if you think that sounds impressive, then just wait another 12 months, when Lexus' ultimate hybrid - the LS500 GT - will appear. Combining a 400bhp 5.0-litre V8 with a 200bhp electric motor, the car will offer at least 600bhp and be targeted at the Mercedes S-Class flagship, the S600L." -AutoExpress It is my prediction that by the end of the decade hybrids will be considered the 'performance option' on high end cars. M, AMG, and Audi Sport will take the base car (let's say 300hp gasoline engine) bump the gas engine (330hp?) and then ask you 'how much do you want?' whereupon they will then bolt on 100-400hp worth of electric motors to your ride. Resulting in 400-700hp 'factory' cars. Apply this to the high end of the market, ferrari et al. and it is not inconceivable that the 612 of 2010 could have 700-900hp (500-600hp V-12 + 2-300hp of electrics). My money is on AMG offering the first 1000hp unit they seem to be more hp drunk than anyone else at the moment.
