Ward's 10 Best Engines Facing Diversity Training

Our pool of 38 nominees for 2015 includes internal-combustion engines powered by three, four, five, six and eight cylinders. We&rsquo;re looking at five diesels; two hybrids; five electric vehicles; a boxer; a CNG flex-fuel V-6, an extended-range EV and a hydrogen-powered fuel cell.

For about a decade, we have declared each year’s pool of nominees for Ward's 10 Best Engines more diverse than the last. 

Each year's assemblage of grunty V-8s, silky V-6s, punchy welterweight 4-cyl. turbos, fuel-sipping hybrids and zero-emission electric vehicles left us convinced the powertrain world was becoming a United Nations summit with no dominant superpower.

This year, we really mean it. 

Our pool of 38 nominees for 2015 includes internal-combustion engines powered by three, four, five, six and eight cylinders. We’re looking at five diesels, two hybrids, five electric vehicles, a boxer, a CNG flex-fuel V-6, an extended-range EV and a hydrogen-powered fuel cell – a first for Ward’s 10 Best Engines. Twenty-one engines are turbocharged while two employ supercharging.

If anyone needs evidence the auto industry is taking a big-tent approach to pressing fuel-economy challenges, look no further than our nominee pool, which illustrates the many directions engineers have been heading in recent years.

The Dodge Challenger SRT Hellcat’s supercharged Hemi V-8 makes an astonishing 707 hp and oozes testosterone in an old-school pushrod sort of way.

At the opposite end of the spectrum is the Hyundai Tucson fuel-cell vehicle, which runs on hydrogen and emits nothing but water vapor. The vehicle is available for lease only in California, where a limited hydrogen fueling infrastructure is taking shape.

But it’s included in this year’s competition in recognition of its far-reaching technology and because automakers may need FCVs to comply with future emissions standards. 

Honda, Toyota and General Motors plan to introduce FCVs in the future. New York is planning to build 100 hydrogen stations by 2020, and numerous other states and countries also are adding to the hydrogen infrastructure. 

4-Cyl. Turbos Rule

If a superpower among this year’s competitors needs to be crowned due to sheer numbers, it’s the turbocharged 4-cyl. engines. There are 14, and certain brands, such as Ford, Hyundai, Volkswagen and Volvo, have multiple entries.

Toyota joins the mix with its first 4-cyl. turbo offered in the U.S. since 1998, the new 2.0L in the Lexus NX CUV. Alfa Romeo also throws its hat in the ring with a mid-mounted 1.7L grenade in the all-new 4C roadster. Welcome back, Alfa.

For those wondering why the new Corvette Z06 is not in contention, it’s priced above our $60,000 cap. And the only new Ford Mustang engine being evaluated is the 2.3L EcoBoost I-4 because the V-6 and V-8 essentially carry over.

The pool of Ward’s 10 Best Engines nominees consists of the 2014 winners plus every new or significantly improved powertrain that meets the price cap and is available in U.S. showrooms during the first quarter of 2015.

Eight WardsAuto editors drive the vehicles in October and November during their routine daily commutes in metro Detroit, the same way most Americans experience their vehicles – going to the grocery store, visiting relatives on weekends, taking kids to school and occasionally wearing down the treads with a thick smoky burnout in a vacant parking lot.

Editors score every engine based on horsepower, torque, drivability, noise mitigation, flexibility, observed fuel economy and onboard technology.

Winners will be announced Dec. 10 at the WardsAuto Outlook Conference in Southfield, MI, (see WardsAuto.com/OutlookConference).

Trophies will be awarded to the winning automakers in January at a banquet during the North American International Auto Show in Detroit.
