The Judging Criteria: More Than Just Horsepower
The selection of the Wards 10 Best Engines and Propulsion Systems is a rigorous process that goes far beyond simple dyno testing. The judging panel, comprised of WardsAuto’s most experienced automotive journalists, evaluates each contender on a comprehensive set of criteria that reflects the complexities of modern vehicle ownership and the evolving demands of the automotive market. This holistic approach ensures that the winning powertrains are not just technologically impressive but also deliver a compelling overall value proposition.
One of the most critical criteria is refinement, which encompasses a wide range of factors that contribute to the driving experience. This includes noise, vibration, and harshness (NVH)—the bane of any powertrain engineer’s existence. A truly exceptional engine or propulsion system should operate with a level of smoothness and quietness that enhances the overall comfort of the vehicle. This is particularly important in the age of electrification, where the absence of engine noise can sometimes highlight other sources of NVH, such as wind and road noise. The judges look for powertrains that manage these factors with sophistication, ensuring that even under hard acceleration, the experience remains refined and controlled.
Performance remains a cornerstone of the evaluation, but it is now viewed through a more nuanced lens. It’s no longer simply about peak horsepower or 0-to-60 mph times, although these metrics certainly play a role. The judges also consider the drivability of the powertrain—how it behaves in everyday driving situations. Is the power delivery linear and predictable? Does the transmission (or lack thereof in a BEV) shift smoothly and intuitively? The torque curve is a critical factor here, with a broad, flat torque curve often being more desirable than a peaky one. A powertrain that feels responsive and effortless in normal driving conditions, while still offering ample performance when called upon, is more likely to impress than one that is merely quick in a straight line.
Efficiency has emerged as a dominant factor in powertrain evaluation, reflecting the growing consumer demand for vehicles that minimize fuel consumption and environmental impact. The judges assess not only the EPA-rated fuel economy but also the real-world efficiency observed during their testing. For ICE vehicles, this involves evaluating how well the engine performs under various driving conditions, including city driving and highway cruising
