There are many reasons why the 2015 Ford Mustang is a big deal. It has a new design, an independent rear suspension, a 2.3-liter four-banger, and, more importantly, it's being sold globally. For the first time since its introduction in 1964, the Mustang is no longer a gray-market car, now reaching enthusiasts through Ford's->ke31 official dealerships. Markets like Europe and China also benefit from the new EcoBoost, four-cylinder powerplant, which requires lower taxes than the bigger and more powerful 5.0-liter V-8.

With the new muscle car->ke507 now ready to hit European streets, Ford Europe is busy promoting it using footage from its testing session at the Lommel Proving Ground in Belgium. FoMoCo just released a 0-to-100 km/h acceleration test, along with data for lateral acceleration, fuel efficiency and CO2 emissions. The figures are for both the GT and EcoBoost versions.

Moving on to the important stuff, the Euro-spec Mustang GT, which comes with 421 PS (415 horsepower) on tap, or 20 horses fewer than its U.S. sibling, can accelerate from 0 to 62 mph in 4.8 seconds with the manual gearbox. The 2.3-liter EcoBoost, on the other hand, rated at 317 PS (312 horses), gets the job done a full second slower, or 5.8 ticks. But while the turbo is significantly slower than the GT, it's also a lot more efficient, returning 35.3 mpg on the U.K. cycle (8.0 l/100 km). The GT is good for 20.9 mpg (13.5 l/100 km).

Would you choose power over efficiency or the other way around?
