BorgWarner suggests Valve-Event Modulated Boost system can offer 6-17% fuel economy benefit over already downsized and turbocharged engines

Green Car Congress

The VEMB system uses a concentric camshaft, blow-down manifold and scavenge manifold to separate the exhaust event into two phases: high-energy blow-down to the turbo without pumping losses, and high-hydrocarbon scavenge to the EGR system. improvement in fuel economy on an E-class vehicle (e.g., Source: Borgwarner.

Are Toyota, Mazda, and Subaru Doing the Right Thing By Snubbing EVs?

The Truth About Cars

Toyota, Mazda, and Subaru conducted a press event designed to explain why they’re walking away from full-blown electrification. The event was hosted by a trio of Japanese CEOs and their top engineers to explain to the world how they planned on tackling emissions regulations without being overwhelmingly reliant on battery electric automobiles.

Advanced ADEPT 48V affordable mild hybrid on path to meet future ultra-low vehicle emissions

Green Car Congress

The final results will be presented at the UK’s LCV2016 event on 14-15 September. The concept of “intelligent electrification” enables highly aggressive engine downsizing and down-speeding beyond what might normally be possible other than through more expensive hybridization approaches.

Toyota continues prepare the market for fuel cell vehicle in 2015

Green Car Congress

Toyota Motor continues to lay the foundation for the introduction of its production fuel cell hybrid vehicle in 2015; the company began work on fuel cell technology in 1992. The output power is more than 100kW, despite significant unit downsizing. kW/L—twice as high as that of its previous FCV, the Toyota FCHV-adv (earlier post).
