Why EU Carmakers Are Digging Their Own Graves — It Is Just A Misunderstanding - CleanTechnica
The article from CleanTechnica discusses why European carmakers, represented by ACEA, appear to be undermining their own future by requesting a delay in the EU's ban on internal combustion engine (ICE) vehicle sales. The author argues that this stance stems from either a misunderstanding of the automotive market or reliance on incorrect information. While ACEA has access to detailed monthly data on vehicle sales across 31 countries and multiple energy types, the problem lies not in the raw data but in how it is interpreted and contextualized. The complexity of metadata, classification rules, and the sheer volume of detailed information often obscures the clear trends, leading to flawed conclusions and decisions. Focusing specifically on the transition to battery electric vehicles (BEVs) in Europe, the author highlights that despite some setbacks—such as a drop in German BEV sales due to subsidy changes—overall BEV adoption is growing steadily, with about 7% growth in 30 countries in 2024. This growth, while modest

Southwest Research Institute (SwRI) has enhanced its heavy-duty hydrogen internal combustion engine (H2-ICE) by integrating a newly designed turbocharger, significantly boosting the engine’s power, torque, and efficiency. The upgraded engine now delivers peak torque of 1,760 foot-pounds and peak power of 440 horsepower, aligning it closely with the performance range of modern long-haul diesel trucks (typically 1,450–1,850 foot-pounds torque and 400–500 horsepower). Additionally, the engine achieves a peak efficiency of 44.0 percent, which is notably high for spark-ignited engines, while maintaining near-zero tailpipe emissions. This advancement was made possible by converting a natural gas engine to run exclusively on hydrogen with minimal modifications, demonstrating the feasibility of adapting existing engine platforms rather than developing entirely new powertrains. A key innovation in this upgrade is the turbocharger’s mechanical linkage to the engine’s crankshaft, allowing variable boost pressure on demand to address

The article from CleanTechnica highlights that the United States must significantly increase electric vehicle (EV) sales—approximately tripling current projections to about 25% of total vehicle sales—to halt the growth of the internal combustion engine (ICE) vehicle fleet. Currently, the US vehicle fleet grows by about 4 million vehicles annually, with EVs making up roughly 8-10% of new sales in 2024. However, this market share is insufficient to reduce the overall number of ICE vehicles on the road, which totaled around 4 million EVs by the end of 2024 and over 296 million total vehicles. Even with EVs eventually dominating sales, it will take years to replace the more than 50 million ICE vehicles added since early EV models like the Volt and Leaf were introduced. The article also notes that factors such as the aging vehicle fleet (average age 12.6 years), removal of emissions and safety inspections in some states, and the end of subsidies are influencing vehicle

Rolls-Royce has commemorated the 100th anniversary of its iconic Phantom model by releasing the Phantom Centenary Private Collection, a highly exclusive series limited to 25 units. This collection marks a significant milestone in the Phantom’s history and serves as one of the final showcases of the internal combustion engine before the brand transitions to an all-electric lineup by 2030. Each vehicle retains the standard Phantom powertrain, featuring a 6.75-liter twin-turbo V12 engine producing 563 horsepower and 664 lb-ft of torque, paired with an 8-speed transmission and advanced chassis technologies like four-wheel steering and road-scanning air suspension. The Centenary model is distinguished by bespoke design elements that celebrate the Phantom’s heritage. The exterior sports a unique two-tone champagne and black paint with glittering metallic particles, complemented by a Spirit of Ecstasy figure crafted from solid 18-carat gold with 24-carat plating. Inside, the rear cabin showcases layered artistic installations combining printed fabric

Runge Cars, a US custom car builder, has developed the Hetzer, a hand-built 5.3-liter air-cooled flat-eight engine designed to revive the classic Porsche air-cooled experience with modern engineering. Featuring dual overhead camshafts, 32 valves (four per cylinder), a 12:1 compression ratio, and a redline of 9,000 rpm, the Hetzer delivers race-inspired performance and a broad powerband. Engineered to fit most air-cooled Porsche 911 models, this engine combines vintage character with advanced CNC machining and motorsport-grade materials, emphasizing balance, performance, and visual appeal. The Hetzer will debut in Runge’s upcoming R3 supercar, a lightweight (1,720 pounds) and analog-focused sports car equipped exclusively with a six-speed manual transmission and rear-wheel drive. The R3’s design features a low-slung front end, circular headlights, and a compact cockpit, with a sweeping rear wing enhancing its performance-oriented aesthetic

Stellantis, the global automaker behind Chrysler, Jeep, and Ram, announced a $13 billion investment plan to enhance its U.S. manufacturing capabilities over the next four years. This initiative includes developing and producing five new vehicles by 2029 across factories in Illinois, Ohio, Michigan, and Indiana. Key elements of the plan are reopening the Belvidere Assembly Plant in Illinois to expand Jeep Cherokee and Compass production, creating over 5,000 jobs, and introducing a new four-cylinder engine (GMET4 EVO) set for production in 2026. Notably, the investment emphasizes traditional gasoline-powered vehicles, including a large SUV and a midsize truck, alongside only one electrified model—a range-extended EV combining a battery with a gas generator, slated for production in 2028 at the Warren Truck Assembly Plant in Michigan. This investment marks a strategic shift for Stellantis, as it scales back its electrification efforts in the U.S. market. Recent decisions include dropping plans

The article discusses the impact of the Trump administration’s policy reversals in July 2025 that aim to slow electric vehicle (EV) adoption in the United States. Key measures include ending federal purchase incentives for new and used EVs, halting the national charging infrastructure program, rescinding California’s zero-emission vehicle mandate authority, and imposing steep tariffs on imported EVs and components. These actions increase EV prices, reduce consumer incentives, and create uncertainty for automakers, resulting in a significant slowdown in the U.S. EV market’s growth trajectory. The expected rapid rise in EV adoption, previously projected to reach critical tipping points in the early 2030s, is now delayed into the mid-2030s, contrasting sharply with faster adoption rates in Europe and China. The article situates this policy shift within a broader series analyzing EV adoption’s diffusion and its effects on internal combustion engine (ICE) service industries. It highlights that without federal support, the U.S. will see a prolonged transition

The Oilstainlab HF-11 is a new American supercar set to debut in 2025, combining hypercar-level performance with innovative drivetrain flexibility. Limited to just 25 units, the HF-11 features two mid-mounted flat-six engine options: a 4.6-liter producing 600 horsepower and a more powerful 5.0-liter twin-turbocharged variant delivering 1,200 horsepower with an extraordinary 12,000 RPM redline. Both engines are paired with rear-wheel drive and lightweight construction, emphasizing driver engagement and dynamic handling. The car’s design draws inspiration from iconic models like the Porsche 911 and Aston Martin Valkyrie, aiming to rival legendary supercars such as the Porsche Carrera GT and Gordon Murray’s T.50. In addition to its internal combustion engines, Oilstainlab is developing an all-electric version of the HF-11 with an estimated 850 horsepower. A unique feature of the HF-11 is the ability to switch between ICE and EV
