VW going turbo-only in 3 to 4 years

This really was a matter of when, rather than if. Volkswagen will apparently be the first manufacturer to phase out naturally aspirated engines in favor of turbocharging its full slate. VW is kind of responsible for ushering in this push towards small-displacement, turbocharged engines that's taken the industry by storm. When it dropped its direct-injection, 2.0-liter turbo in the 2005 GTI it demonstrated that strapping an iron long to an engine can enhance the powertrain as a whole. VW made fuel economy gains, while also giving a linear, non-laggy turbo experience that it has replicated, model-after-model, to this day.
Speaking with The Detroit News, Volkswagen's executive Vice President of Group Quality, Marc Trahan, told the paper that, "We only have one normally aspirated gas engine, and when we go to the next generation vehicle that it's in, it will be replaced. So three, four years maximum."
Really, it's hard to get teary-eyed about either of these engines going away. VW has access to smaller powerplants that could easily match the performance of the 2.5 five-cylinder and the 3.6 V6, while gobbling up less fuel and providing a better driving experience. What we are sad about is that a similar statement about the extinction of NA engines came from the Vice President of Powertrain Engineering at Ford, Joe Bakaj. We'd certainly get teary-eyed over a world without Ford's excellent 5.0-liter V8.

2015 Ford Mustang potentially 'leaked' by Car and Driver

Few upcoming debuts have been as eagerly anticipated as the all-new Ford Mustang that's expected to debut shortly as the Mustang's 50th anniversary year approaches. Well, Car and Driver magazine would have us wait no longer as it claims to be leaking Ford's new global pony car early.
Of course what you're looking at is just as likely to be a composite rendering based on what C/D projects the new Mustang to look like, but to our eyes it looks spot on. Combining design traits from the Evos Concept with classic Mustang signatures and Ford's Aston-inspired grille treatment, C/D's images - including a complete 360-degree digital navigator - show a Mustang not only for the modern era, but also for global distribution, taking a quintessentially American car to markets its predecessors were never designed for.
Those global considerations are expected to spell the demise of the outgoing Mustang's holdout live rear axle in favor of an independent suspension, and a slight constricting of the exterior dimensions. And thanks to a separate leak, coming from a digital survey, we have apparent confirmation of what will power the new pony car. While the existing 3.7-liter V6 and 5.0-liter V8 engines will apparently carry over with only slight adjustments in output, the survey confirms a new 2.4-liter turbo four will be positioned in between them, offering slightly more power than the V6 but markedly improved fuel economy for a manageable $560 premium over base.
