This year’s Wards 10 Best list, due to be officially unveiled in mid-September and celebrated at an industry gala in Dearborn, Michigan, on October 22nd, represents more than just a compilation of powerful motors. It signifies a critical inflection point where automakers are balancing the immediate demands of performance and efficiency with the long-term trajectory toward electrification. The judges tasked with evaluating these contenders—WardsAuto Lead Editor Christie Schweinsberg, WardsAuto Editor Jim Irwin, and Contributing Editors Bob Gritzinger, Gary Vasilash, Drew Winter, and Dave Zoia—face a formidable challenge: to discern which technologies not only deliver immediate gratification in terms of horsepower and torque but also offer a glimpse into the future of sustainable mobility.
As we delve into the 2025 Wards 10 Best Engines and Propulsion Systems nominees, we are essentially taking a pulse of the industry’s heartbeat. The sheer diversity of the list is striking. We see the continued refinement of the turbocharged four-cylinder, a workhorse that has become the default for efficiency-conscious automakers. Yet, this familiar architecture is being augmented with sophisticated mild-hybrid systems that extract more energy from braking and reduce parasitic losses, pushing the boundaries of what was once considered a basic configuration. Simultaneously, the V-8 engine, long the symbol of American automotive muscle, is making a defiant stand, albeit in highly hybridized forms that blend raw power with newfound environmental responsibility.
The most significant narrative, however, is the ascendancy of the battery electric vehicle. The 2025 nominees feature a substantial contingent of BEVs, ranging from mainstream utility vehicles to high-performance supercars. This isn’t just a token representation; it’s a clear signal that electric propulsion is no longer a niche offering but a central pillar of automotive innovation. Automakers are investing billions into battery technology, charging infrastructure, and software development, all in a bid to capture market share in the EV era. The inclusion of multiple BEVs on the Wards list suggests that the industry is moving beyond the early adopter phase, with electric vehicles now capable of delivering on the performance and refinement expectations of the mainstream consumer.
The Enduring Allure of the Internal Combustion Engine
Despite the relentless march of electrification, the internal combustion engine refuses to fade into obsolescence. In fact, the 2025 Wards 10 Best nominees demonstrate that manufacturers are extracting every last drop of potential from ICE technology. The familiar turbocharged four-cylinder is ubiquitous, appearing in vehicles as diverse as the Acura ADX and the Volkswagen Tiguan. These engines are no longer the crude, thirsty units of yesteryear. Through advancements in direct injection, variable valve timing, and turbocharging, they now offer a compelling balance of power, efficiency, and refinement that appeals to the pragmatic consumer.
One of the most interesting trends in this segment is the integration of mild-hybrid systems. This technology, which typically involves a small electric motor-generator and a 48-volt battery, provides a subtle but significant boost to the ICE. It allows for smoother engine restarts, enables seamless start-stop functionality, and recaptures energy that would otherwise be lost as heat during braking. For the everyday driver, this translates to a more refined driving experience and noticeable fuel savings without the complexity or range anxiety associated with fully electric vehicles. The Honda Civic Hybrid and the Mazda CX-50 HEV are prime examples of this philosophy in action, proving that hybridization can enhance, rather than compromise, the driving experience.
However, the ICE is not just surviving in the mainstream; it is also roaring back in high-performance applications. The 2025 list includes some truly formidable V-8 powerplants. The Chevrolet Corvette ZR1’s 5.5L twin-turbo V-8 represents the pinnacle of ICE engineering, combining massive displacement with forced induction to deliver supercar-level performance. Similarly, the BMW M5’s 4.4L twin-turbo V-8 PHEV demonstrates how traditional muscle can be tamed and enhanced through electrification. These vehicles cater to the enthusiast who craves the visceral thrill of a large displacement engine—the sound, the torque, the raw power—while also embracing the improved efficiency and emissions benefits of hybrid technology. It’s a case of having your cake and eating it too, a proposition that resonates deeply with the performance-oriented buyer.
Hybridization: The Bridge to an Electric Future
If the internal combustion engine represents the past and the battery electric vehicle the future, then hybrid technology is the crucial bridge connecting the two. The 2025 Wards 10 Best nominees showcase a remarkable breadth of hybrid approaches, from simple mild-hybrid systems to sophisticated plug-in hybrids (PHEVs) and full hybrids. This diversity reflects the industry’s recognition that there is no one-size-fits-all solution to the electrification challenge. Different market segments and consumer needs require different approaches, and hybridization offers the flexibility to tailor powertrain solutions to specific applications.
Full hybrids, such as the Toyota RAV4 Hybrid, combine an ICE with an electric motor and battery pack that can propel the vehicle on electricity alone for short distances. These systems excel in urban driving conditions, where stop-and-go traffic allows for frequent regenerative braking and electric-only operation. The result is a significant reduction in fuel consumption and emissions without the need for external charging infrastructure. For the mainstream consumer, this represents the ideal entry point into electrification—it’s familiar, practical, and requires no change in behavior.
Plug-in hybrids take the concept a step further by offering a larger battery pack that can be charged from the electrical grid. This allows for a substantial all-electric range, often sufficient for daily commuting needs. When the battery is depleted, the vehicle reverts to traditional hybrid operation, ensuring that range anxiety is never a concern. The BMW X3 2.0L turbo I-4 w/ mild hybrid system and the Mercedes-Benz GLC 350e 2.0L turbo I-4 PHEV are excellent examples of this technology, offering the best of both worlds: the ability to drive emissions-free for typical daily commutes and the flexibility of a gasoline engine for longer journeys. For consumers who are not yet ready to commit to a full EV but want to reduce their environmental impact, PHEVs represent a compelling compromise.
The most advanced hybrid systems are found in luxury and performance vehicles, where the focus is on enhancing both efficiency and performance. The Genesis GV80 Coupe 3.5L turbo V-6 w/ electric supercharger and the Lexus LX 700h 3.4L turbo V-6 HEV demonstrate how electrification can be used to extract more power and torque from the engine. The electric supercharger in the Genesis, for instance, eliminates turbo lag and provides instant torque, while the hybrid system in the Lexus enhances the already formidable V-8 with electric power, resulting in a vehicle that is both powerful and surprisingly fuel-efficient for its size.
