Researchers used a functional-connections-based method to simulate 30 million Earth–Moon routes and found a previously hidden gravity-assisted trajectory that saves about 58.8 m/s of delta-v over the prior cheapest path, enabling cheaper Moon travel and uninterrupted Earth communication; further work could include solar gravity to push costs even lower.
Honda and Acura teased next-generation hybrid prototypes with a new platform, promising over 10% better fuel efficiency. The Honda sedan and Acura SUV are set to go on sale within two years, primarily in the US as part of a broader North American push. Honda aims for 15 hybrid models by 2030 and expects cost reductions with a new powertrain, funded by about 4.4 trillion yen (~$28B) for hybrids/gas models, plus roughly 0.8 trillion yen (~$5B) for future EVs; meanwhile, several EVs were canceled and Honda will continue EVs in Japan/Asia while reassessing the US strategy.
A Voronoi visualization estimates monthly gas costs by state using April 15, 2026 prices and average miles driven at 25.6 mpg. Wyoming leads at about $279 per month largely due to long drives (roughly 1,830 miles per month), while New York spends about $132 monthly because of dense, shorter trips (around 817 miles per month). The national average is about $190. The main insight is that distance traveled, not just gas prices, drives most Americans’ fuel bills, with rural states typically paying more despite lower prices.
BMW shifted from its older non-sequential Twin Turbo setup on the 3.0-liter inline-sixes to a single twin-scroll turbo (the N55) to cut fuel consumption and emissions, simplify under-hood packaging, and reduce maintenance costs. The twin-scroll design improves exhaust-pulse efficiency and speeds up turbo spool, a move BMW highlighted when switching from the N54 to the N55 around 2009; some engines in other brands still use two turbos for packaging or performance gains, such as banked layouts in the Audi S4 or Porsche 911.
Delta Air Lines will add 30 Boeing 787-10 Dreamliners to its widebody fleet, introducing a new aircraft type to support international growth, offering about 25% better fuel efficiency per seat, larger premium cabins and enhanced onboard amenities powered by GE’s GEnx engines as part of a broader fleet modernization and international expansion plan.
A viral video shows a Toyota Corolla filling from empty for $22.61, highlighting strong fuel economy (roughly 30–40 mpg, over 50 mpg for hybrids) and noting 2026 gas prices are forecast to average about $2.97 per gallon with regional variation; the piece also contrasts sedan efficiency with SUVs and mentions potential yearly savings from choosing a fuel-efficient car.
President Trump plans to weaken fuel efficiency standards for cars and trucks, potentially impacting environmental policies and automotive industry regulations.
3-cylinder engines are more fuel-efficient and lighter than 4-cylinder engines, making them ideal for compact vehicles, but they tend to have rougher idling and less power at high speeds. They also have fewer parts, which can reduce maintenance costs, but may not provide the smoothness or acceleration some drivers desire.
A century after its initial demonstration, Flettner rotor technology, which uses spinning towers to harness wind for propulsion, is gaining popularity in the maritime industry, with at least 35 ships now using the technology to reduce fuel costs and emissions, driven by modern needs for decarbonization and advancements in materials and AI.
Consumer Reports' top-rated SUVs for 2025 include the Subaru Forester, Hyundai Tucson Plug-In Hybrid, Subaru Outback, Toyota Crown Signia, and Toyota RAV4 Plug-In Hybrid, with highlights on their fuel efficiency, reliability, and practical features, catering to different preferences for hybrid and traditional models.
Recent data shows that charging a Tesla for a month is significantly cheaper than paying for gas to fuel a Chevy Silverado, with Teslas achieving much higher miles per gallon and monthly costs ranging from $49 to $64, compared to around $137 for the Silverado, highlighting the cost savings of electric vehicles.
The 2026 Jeep Cherokee introduces its first hybrid powertrain, offering 210 hp and up to 37 mpg combined, aiming to attract new customers and compete with other hybrid SUVs, while continuing Jeep's electrification success with models like the Grand Cherokee 4xe and Wrangler 4xe.
The 2026 Jeep Cherokee has been redesigned as a larger, more luxurious hybrid SUV with a 210 hp powertrain, offering improved interior space, advanced technology, eco-friendly materials, and a starting price of $36,995, aiming to compete in the hybrid crossover segment.
Cylinder deactivation is a technology used by automakers to improve fuel efficiency by shutting down some engine cylinders when full power isn't needed, but its real-world benefits depend on driving conditions and habits, with potential issues like vibrations and misfires affecting performance.
Many new cars no longer include spare tires to improve fuel efficiency and reduce costs, with options now including space-saving spares and run-flat tires, though these come with trade-offs like higher costs and potential safety concerns.
