I find it alarming how ignorant people are when they think you need AWD and a turbo to do anything in a performance car. In Alaska I agree but in other parts of the world that application doesnt hold nearly as much of a benefit as you would think.
Just remember rear wheel drive dominates in the performance world in everything except rally cross.
The first 1 million dollar car was a mid engine rear wheel drive naturally aspirated Mclaren F1 and set the land speed record for fastest street legal vehicle at over 240 MPH and has a huge racing legacy. The first car to beat the speed record over 10 years later was the bugatti veyron which gets its face kicked in by cars with 2/3rds of the power on a race track.
AWD only matters where it is a niche in the racing world when it comes to the top cars in the industry.
Forced induction is never necessary unless you are trying to meet certain weight parameters and even then its debatable and nobody in their right mind would prefer turbo lag over an equally powerful naturally aspirated power plant if you can build the cars around the same or similar parameters when it comes to weight, handling, power and dimensions.
The BRZ is much lighter and does not need the same kind of power as a WRX/STI to do what its intended purpose is. Guaranteed a BRZ will smoke you in autox and you will think differently after. If you haven't driven a light weight RWD naturally aspirated car in your life time then I suggest you try it out someday. Easy example regardless of how pathetic they look is picking up a RX-7, Miata, MR2/MRS or S2K.
I now welcome the BRZ/FR-S to the wonderful list of Japanese RWD sports cars that many enthusiasts will appreciate.
