Wards 10 Best Engines and Propulsion Systems 2025: The Future of Automotive Power is Here
The automotive industry is in the midst of a seismic shift, moving away from traditional internal combustion engines (ICE) toward electrification and alternative propulsion systems. This transformation is not just about meeting regulatory requirements; it’s about redefining the driving experience, enhancing performance, and pushing the boundaries of engineering. WardsAuto, a leading authority in automotive trends, has once again recognized the innovators and visionaries who are shaping this new era with its annual 10 Best Engines and Propulsion Systems awards.
The 2025 Wards 10 Best Engines and Propulsion Systems shortlist represents a diverse and exciting cross-section of the automotive landscape. From high-performance PHEVs to advanced BEVs and efficient hybrid systems, this year’s nominees showcase the incredible progress being made in automotive technology. The winners, announced in mid-September and celebrated during a ceremony in Dearborn, MI, will undoubtedly set the benchmark for the industry for years to come.
The Evolution of Automotive Power
For decades, the Wards 10 Best Engines list focused almost exclusively on traditional ICE powertrains. However, as the industry has evolved, so too has the awards program. This year’s list reflects the reality of the modern automotive market, where electrification is no longer a niche trend but a mainstream reality.
The Rise of Electrification
One of the most striking trends in this year’s Wards 10 Best Engines and Propulsion Systems nominees is the sheer number of electric vehicles (EVs). Battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs) dominate the list, signaling a clear shift in consumer preferences and manufacturer priorities.
The WardsAuto judging panel, comprised of experienced automotive journalists, has the unenviable task of evaluating these advanced powertrains. “This year’s list is a testament to the incredible innovation happening across the industry,” says Christie Schweinsberg, WardsAuto Lead Editor. “We’re seeing powertrains that deliver exhilarating performance while also being incredibly efficient and environmentally responsible.”
The criteria for selection are rigorous. Judges evaluate each vehicle on its own merits, considering factors such as:
Performance: Acceleration, power delivery, and overall driving dynamics
Efficiency: Fuel economy or electric range and energy consumption
Refinement: Noise, vibration, and harshness (NVH) levels
Technology: Integration of advanced powertrain technologies
Value: Overall package considering performance, efficiency, and price
Hybrid Systems: The Best of Both Worlds
While BEVs continue to capture headlines, hybrid systems are quietly becoming the go-to solution for many consumers. These systems combine the benefits of electric propulsion with the range and convenience of traditional ICEs, offering a compelling package for those who want to reduce their environmental impact without the limitations of early EVs.
The 2024 returning winners, such as the Ford F-150 3.5L turbo V-6 HEV and the Toyota GR Corolla 1.6L turbo I-3, demonstrate the maturity of hybrid technology. These vehicles prove that hybrids are not just fuel-efficient commuter cars; they can also deliver impressive performance and driving pleasure.
A Deep Dive into the 2025 Nominees
The 2025 Wards 10 Best Engines and Propulsion Systems shortlist features a remarkable range of vehicles, each representing a different facet of the industry’s evolution. Let’s explore some of the most notable contenders:
The BEV Revolution
The list is packed with all-electric contenders, each pushing the boundaries of what’s possible with battery technology. The Cadillac Escalade IQ BEV and the Jeep Wagoneer S BEV represent the electrification of iconic American SUVs, promising to deliver the luxury and capability these brands are known for, but with zero tailpipe emissions.
The Lucid Gravity BEV and Polestar 4 BEV showcase the cutting edge of EV design and engineering, offering sleek aerodynamics, impressive range, and advanced technology. Meanwhile, the Hyundai Ioniq 5 N BEV and Kia EV9 GT Line BEV, both returning winners, continue to set the standard for performance-oriented EVs.
“The performance of these BEVs is simply stunning,” notes Jim Irwin, WardsAuto Editor. “The instant torque delivery and seamless acceleration are unlike anything we’ve experienced with traditional powertrains. It’s a completely different driving experience.”
PHEVs: The Performance Edge
For those seeking the best of both worlds, plug-in hybrids offer a compelling solution. The BMW M5 4.4L twin-turbo V-8 PHEV and the Mercedes-AMG E53 3.0L turbo I-6 PHEV represent the pinnacle of PHEV technology, combining the raw power of V-8 and I-6 engines with electric assistance for an exhilarating driving experience.
These vehicles demonstrate that PHEVs are not just about efficiency; they’re also about performance. The electric motors provide instant torque for quick acceleration, while the turbocharged ICEs deliver power at higher speeds, creating a seamless and dynamic driving experience.
The Evolution of ICE Technology
While electrification is on the rise, traditional ICE technology continues to evolve. The Buick Enclave 2.5L turbo 4-cyl. and the Dodge Charger Daytona BEV (which also features an electric variant) showcase the advancements being made in ICE engineering. These engines are more efficient, more powerful, and more refined than ever before, thanks to advancements in turbocharging, direct injection, and engine management systems.
The Nissan Armada NISMO 3.5L turbo V-6 and the Ram RHO 3.0L turbo I-6 high output demonstrate that there’s still plenty of life left in the internal combustion engine, especially in the truck segment where towing capacity and power are paramount.
The Judging Process: A Rigorous Evaluation
The Wards 10 Best Engines and Propulsion Systems selection process is a rigorous and comprehensive one. Over several months, the WardsAuto judging team drives and evaluates dozens of vehicles, putting each powertrain through its paces in real-world driving conditions.
“We spend countless hours behind the wheel, testing these vehicles on everything from city streets to highways and winding roads,” explains Drew Winter, WardsAuto Contributing Editor. “We’re looking for that ‘wow’ factor, that moment when you realize you’re experiencing something truly special.”
The evaluation criteria have evolved to reflect the changing automotive landscape. While NVH levels and refinement remain important, the judging team is also looking for how well these powertrains integrate with the vehicle’s overall design and technology.
“It’s not just about the engine or motor anymore,” adds Dave Zoia, WardsAuto Contributing Editor. “It’s about the entire propulsion system. How does the electric motor work with the ICE? How does the battery management system optimize performance and efficiency? These are the questions we’re asking.”
Trends Shaping the Future of Automotive Power
The 2025 Wards 10 Best Engines and Propulsion Systems nominees highlight several key trends that are shaping the future of automotive power:
