Subcompact sales slump, yet again

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.

Ford reveals EcoBoost-powered Riley prototype for Daytona 24

It's not the first time Ford has participated in the Daytona Prototype class as an engine supplier, but in revealing this new EcoBoost V6-powered Riley Technologies prototype for the new United SportsCar Championship, Ford is making a statement: "We want to show Ford EcoBoost's capabilities as an engine that provides both performance and fuel economy, on and off the track," says Jamie Allison, director of Ford Racing.
In addition to supplying the 3.5-liter twin-turbocharged V6, Ford had its production designer Garen Nicoghosian give the racecar brand-inspired design cues with support from Ford Racing chief aerodynamicist Bernie Marcus.
The car is scheduled to compete at next year's Rolex 24 at Daytona on January 25-26, but before that, Michael Shank Racing is working with Ford at another goal. Driving his Ford Thunderbird, NASCAR champion Bill Elliott set the track's top speed record at 210.364 miles per hour during a qualifying run for the Daytona 500 - way back in 1987 -- and Ford thinks it's about time for that record to fall. What better time the introduction of this new Ford-powered Daytona Prototype? Michael Shank Racing plans to use the twin-turbo V6-powered racer to beat Elliott's record, and it expects to begin prepping for the top-speed run on October 9.
