Formula 1 with ERS: For this year’s Formula 1 season, FIA changed the regulations of the Energy Recovery System significantly. Renault is the first to publish details about their latest race engine that is now capable of giving an extra boost of 120 kW, mainly regenerated from braking and by the exhaust system.,

Silicon-carbon composite: EnerG2 has introduced a composite of silicon and carbon to improve the performance and capacity of lithium-ion batteries. The company claims that the new anode composite will improve the cycle times of batteries by a factor of five.

BYD put to the test: In Canada, a 40-foot BYD electric bus has completed the first ten months of road trials rather successfully. Supplemented by a small diesel-powered heater, the bus was able to achieve an average consumption of 15 kWh per 100 km with air conditioning and full passenger loads. Société de transport de Montreal (STM) will continue tests until spring of 2014.

Hybrid versus Diesel: Although comparisons between diesel and petrol-powered cars are always like comparing apples and oranges, it is worth mentioning what Whatcar? just found out. In the magazine’s most recent real-world MPG test of executive cars, the Lexus IS 300h not only was the most powerful car but also came out as winner by beating all four German diesel competitors in terms of fuel efficiency.,
