General Motors has filed a patent for a new two-stage turbocharger that should increase performance and negate lag.
There's some concern among a portion of drivers that the move from big displacement, naturally aspirated performance engines towards smaller, turbocharged units is somehow diluting the experience behind the wheel. Xcar Films tries to suss out whether that's actually the case during its drive of the Mercedes-AMG C63 S.
An investigation from Navigant Research predicts less than 50 percent of new vehicles globally will use conventional gasoline-fueled engines by 2017. However, the study's definition even takes turbocharging into account as being outside the norm. The report also estimates that stop/start systems will be in nearly 60 percent of models by 2025.
Despite the growing trend of automakers offering diesel-powered or electrified powertrains, there's still a whole lot that can be done with the good-old gasoline internal combustion engine. And at Hyundai, that's exactly what's being worked on – new gasoline engine technologies that improve both performance and efficiency. During an event at the automaker's technical center in Superior Township, MI on Friday, Hyundai gave Autoblog a glimpse into the future, offering up preliminary details
Turbocharging isn't really Toyota's specialty, and the Japanese automaker isn't being shy about acknowledging it. Koei Saga, a senior managing officer in charge of drivetrain research and development, says that eschewing turbos and increasing displacement of engines using the Atkinson cycle can produce better power gains without sacrificing fuel economy, Automotive News reports.
Aside from its hybrid technology, Toyota has fallen behind the competition in terms of vehicle powertrains which could leave popular cars like the Toyota Camry and Toyota RAV4 lagging behind the competition. While most of its rivals have started using gasoline direct injection, turbochargers and some have moved to Continuously Variable Transmissions (CVT) to balance performance and fuel economy, many Toyota models are still using underpowered engines and outdated transmission technology.
