Fuel economy is the name of the game these days and the V8 engine simply doesn't cut it anymore. With automakers ditching larger displacement engines for smaller, turbocharged ones, the V8 is disappearing in sedans, while it is still fairly available in the pickup and big SUV class, as well as muscle cars and exotics. There is no V8 in the new Cadillac flagship XTS sedan, nor in the biggest Lincoln today--the MKS sedan. While we do love getting some more MPGs, it's really a shame that we one day won't be able to experience the joy that comes with hearing the roar of 8-cylinders.
An 8-cylinder engine is still offered in big sedans like the Lexus LS460, Mercedes S Class, BMW 7 Series, Audi A8 and Jaguar XJ. But those automakers report that the take rate for the V8 is dwindling, with more buyers interested in the smaller V6, more fuel efficient, trim levels.
