Finally, the Engine It Deserved
n our September 2012 small CUV comparison test, in which the Ford Escape edged the Mazda CX-5 for top honors, the overwhelming consensus among the judges was that had the Mazda had more oomph, it would have won. As Jonny Lieberman so eloquently concluded, "Engine notwithstanding, we liked almost everything about the CX-5. If Mazda could add a little extra power, well, winner, winner, Mazda chicken dinner." With a naturally aspirated 2.0-liter Skyactiv I-4 producing 155 horsepower and 150 lb-ft of torque, the FWD CX-5 needed 9.4 seconds to saunter from 0 to 60 mph and 17.1 seconds at 79.9 mph to nudge the quarter mile. That's 0.5 and 0.4 second slower, respectively, than the times for the 173-hp, 184-lb-ft Escape. Zoom-zoom? Not so much.
Just one model year after its introduction, though, Mazda is adding an old-school enhancer -- displacement -- aimed at giving the sporty CUV the muscle to match its athletic chassis. About the size of an average Coke bottle, the half-liter of extra engine volume gives the new 2.5-liter Skyactiv I-4 the much-needed energy to make another run at the Escape. Output for the 2.5, which is shared with the 2014 Mazda6, is rated at 184 hp at 5700 rpm and 185 lb-ft at 3250, with both power and torque peaks realized earlier in the power band than in the 2.0. Similar to its smaller sibling, the 2.5 boasts direct injection and a 13.0:1 compression ratio, and runs on 87 octane. But that's about where the similarities end. Both bore and stroke are unique to each engine, and Mazda notes that only a handful of components are shared between the two.
