Electrification continues to power the Wards 10 Best Engines & Propulsion Systems list, with six electrified vehicles, including three battery-electrics and three hybrids, earning 2023 honors, along with four new or significantly improved internal-combustion powerplants.

This year, Wards editors evaluated 32 vehicles: 13 ICEs, 10 BEVs and nine hybrids. The hybrid count included five plug-in hybrids and four hybrids.

Of the 13 purely internal-combustion engines tested, there were five 4-cyl. engines, four 6-cyl. engines (all inline), three V-8s and one 3-cyl. engine. All of the ICEs except two of the V-8s were turbocharged.

The Wards 10 Best list has recognized 29 years’ worth of propulsion systems, with scoring based on horsepower, torque, NVH management, observed efficiency and new technology onboard. A price cap for nominees that had been in place since 1995 was removed in 2021; value remains part of the criteria, however.

While evaluating the vehicles, only powertrains that are all-new or significantly improved are eligible for testing. The 2022 class of Wards 10 Best Engines & Propulsion Systems winners were eligible to return, but only two returnees, the Lucid Air Touring BEV and the Hyundai Ioniq 6 BEV (in place of the Ioniq 5 with the same system), earned repeat honors.

Clearly, with the pace of electrification and advances in internal combustion, it’s a rare propulsion system that can impress our judges for more than a year or two. Turnover in powertrains is at a peak moment, exemplified not only by the rush of electric propulsion systems coming to market, but also in internal-combustion development.

“The market may be starting to cool when it comes to battery-electric-vehicle adoption, but automakers are forging ahead with constant innovation in BEVs that promise increased range and efficiency and ever-quicker charging systems,” says Bob Gritzinger, WardsAuto editor-in-chief.

“At the same time, no one is lifting off the internal-combustion pedal, with more than a dozen all-new or significantly upgraded ICEs on our nominee list, and two big, naturally aspirated V-8s making our winners’ list,” he notes. “We’re seeing the end of the ICE era, but those engines aren’t going out without making some noise.”
