Toyota may return to F1 under Lexus banner

A new report in from the website Club Lexus claims to have insider knowledge about a return to Formula One racing by Toyota, this time under the auspices of the Lexus brand. Toyota competed in F1 from 2002 through the 2009 season. That final year saw the team return competitive, if inconsistent results, but the larger economic woes in the automotive market made a decision to pull the plug relatively easy at the time.
Now, citing recent interviews with Toyota executives and insider sources, Club Lexus says that the move to re-enter F1 for the 2014 season is "all but finalized." The choice to go with the Lexus nameplate over Toyota makes some sense, too, considering the success that rival Infiniti has had in recent years through its partnership with Red Bull Racing. Further, the emerging Lexus identity as a performance car builder, with a strong background in hybrid vehicles, could help the F1 move resonate with buyers.
A few technological factors and formula changes within F1 offer some credence to the Lexus rumor, too. F1 will increase the available capacity of KERS from 60kW to 120kW, a change that theoretically benefits the hybrid-savvy Toyota. What's more, 2014 will see a switch from the current 2.4-liter V8 engines to 1.6-liter turbocharged V6s. A Lexus team that goes racing in 2014 will be on a level playing field with the rest of the grid then, with all teams adjusting to and continuing to develop the new engines.

2016 Toyota Mirai Fuel Cell Vehicle likely to get 60 MPGe

Toyota isn't talking about the Mirai's fuel economy just yet, but that doesn't mean we can't make an educated guess. And we do so by looking at the competition and knowing that the DOE says that "One kg of hydrogen is roughly equivalent to one gallon of gasoline." For now, the Mirai's H2 competition means the 2015 Hyundai Tucson Fuel Cell. It can carry 5.64 kg of hydrogen and has a range of 265 miles. If we do the division there (265/5.64) we get 47 miles per gallon equivalent (MPGe). The DOE says that the miles/kg values are 49 combined, 48 in the city and 50 on the highway while Hyundai lists the official MPGe estimates as 50 combined, 49 city and 51 highway. The simple math gets us pretty close to these official numbers. Or take the 2014 Honda FCX Clarity. With a range of 231 miles and a max of 3.92 kg of hydrogen on board, division gets us to 59 MPGe. Officially, it's rated at 59 miles per kg (combined), with 58 in the city and 60 on the highway. In other words, simple math is a reliable way to calculate rough MPGe. So, we know that the Mirai can hold five kilograms of hydrogen on board and that the car has a 300-mile range. We don't even need a calculator to figure out that the Mirai is looking at 60 MPGe. Interestingly, that might be what the next-gen Prius will get.

Toyota to buck engine downsizing trend, may go larger and turbo-free

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.
Toyota is investing heavily in larger-displacement Atkinson-cycle engines in addition to turbocharged engines, but Saga doesn't think the automaker will use turbocharging across many product lines. He apparently remains unconvinced that the technology "makes the world better."
In Toyota's eyes then, Atkinson cycle engines do make the world better, and here's how. Their pistons complete four processes - intake, compression, power and exhaust - in one revolution of the crankshaft, and the power stroke is longer than the compression stroke. Traditional Otto cycle engines require two crankshaft revolutions to accomplish those same four operations and have equal-length compression and power strokes. Atkinson cycle engines are more efficient, but less power dense, though increasing displacement can offset that shortfall.
