Over the last few years, 52-percent of 'Stangs came with the 4.6-liter V8, but rising fuel prices and the fact that enthusiasts bought early has brought that number back down to 45-percent, so Ford will be reducing the number of 2008 Mustangs it builds with a V8.
We're sure the excessive amount of special edition models helped fuel the initial fire for the V8, and we expect the eight cylinder engine to comprise over 50-percent of sales once again when a refreshened Mustang hits the market before the end of the decade. That said, we recall that Ford's newish 3.5L V6 is suited to rear-wheel-drive, and expect that engine or a version of it, coupled with a six-speed automatic, to land in the Mustang's engine bay eventually. After all, Ford promised that the 3.5L V6 would power 1 in 5 of its models by 2010.
