Toyota still wants Tesla's battery help, still evaluating RAV4 EV program

Tesla Motors said earlier this month that the agreement it has with Toyota to supply battery packs for the Toyota RAV4 EV SUV would be finished by the end of the year. The deal is done, but Toyota is now singing its best version of Baby, Please Don't Go. The Japanese automaker may look to extend the battery-pack agreement with California-based Tesla, Automotive News says, citing comments made by Osamu Nagata, who heads Toyota's manufacturing and engineering in North America. Nagata also complimented Tesla for its "clear business strategy." Toyota, which owns 2.5 percent of Tesla, started the RAV4 EV collaboration in 2012, in which Tesla was to make about 2,600 battery packs for the all-electric SUV. That agreement was estimated to be worth about $100 million. "We are also evaluating the RAV4 EV program and will have more to say at a later date" – Toyota "We have a good relationship with Tesla and will evaluate the feasibility of working together on future projects," Toyota said in a statement e-mailed to AutoblogGreen. "We are also evaluating the RAV4 EV program and will have more to say at a later date." And while Toyota hasn't quite met initial sales expectations – it sold about 1,600 of the RAV4 EVs through this spring – the company expects to reach 2,500 by the end of the year. And the partnership did generate about $15 million in revenue for Tesla, according to that company's first-quarter letter to shareholders. That said, Tesla is obviously focusing its battery-making efforts on its own models.

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.

Shuttle-hauling Tundra finds permanent home in science exhibit

The idea of lifting a full-size pickup truck completely off the ground by hand might seem as likely as, say, said pickup truck towing a 150,000-pound space shuttle, but... hurray, physics! The same Toyota Tundra that towed the Space Shuttle Endeavour to its final resting place at the California Science Center is now on permanent display there as an exhibit that shows how a lever works.
Like all levers, this exhibit uses a fulcrum allowing people other than Superman to lift the 5,625-pound pickup (plus an extra 1,000 pounds for the rig). That's almost as impressive as the Tundra pulling 17 times its rated towing capacity back in October. Regardless, Toyota is once again cashing in on the publicity stunt and visitors to the science center get a live demonstration of a simple machine - we call that a win-win.
