Toyota unveils two new small displacement engines

Toyota introduced a pair of brand-new engines in Japan today, that it says will eventually spawn 14 different variants by 2015. Where these two engines stand out in today's world, is that neither mill boasts direct injection, and both are naturally aspirated.
The larger of the two is a 1.3-liter, while the smaller engine, a 1.0-liter, was developed in collaboration with Daihatsu. What makes these two unique is that they both use the Atkinson cycle. Now, we aren't going to bore you by explaining just what this is - there's Google for that. Suffice it to say, Atkinson engines are highly efficient, but that efficiency comes by sacrificing power. That's why they're so popular in hybrids, which can offset the power losses.
This focus on fuel efficiency extends throughout the new engines, which also benefit from tweaks like a cooled exhaust gas recirculation system and a trick intake port, while the 1.3 employs Toyota's iE variant of variable valve timing. Both engines can be fitted with stop-start tech. According to Toyota, when fitted with stop-start the 1.3 should provide around a 15-percent bump while the 1.0-liter will increase economy around 30 percent, when they arrive on the road.

Toyota FCV Concept comes one step closer to reality

When Toyota first conceptualized a gasoline-electric hybrid vehicle for mainstream Americans to drive, the initial response was pretty skeptical. Still, through relentless engineering and solid product after solid product, Toyota has built the Prius brand into the dominant force in the hybrid car market.
Something like that plan of attack is what the Japanese company is preparing for hydrogen fuel cell vehicles, as well, and that attack is seeing a critical salvo fired today with the debut of this FCV Concept at the Tokyo Motor Show.
Though there's nothing substantive to be said about rumors of a 300-mile range or a sticker price around $50,000, the FCV concept does offer a few technical details. The sharp-beaked concept makes use of two high-pressure hydrogen tanks and boasts a power output density of three kilowatts per liter.

Toyota reveals updated TS040 Hybrid LMP1 for 2015 [w/videos]

Toyota has yet to defeat Audi at Le Mans. In fact, nobody has in the past fifteen years except for Peugeot (which won in 2009) and Audi's own sister company Bentley (which took the checkered flag in 2003). But Toyota did win the broader FIA World Endurance Championship last season, beating its German rivals in five out of eight rounds. That means the Japanese automaker is returning to top-level endurance racing this season as the reigning champions, and this is the car with which it aims to defend its title. The 2015 Toyota TS040 Hybrid is closely based on last year's winning version, but has been updated to comply with the latest tweaks to the regulations. A new crash structure meant redesigning the front end, the aerodynamics package has been thoroughly revised, the suspension reconfigured and extra weight has been cut. All told, Toyota says it redesigned 80 percent of the parts on board. Each team running a hybrid prototype has an array of choices over what combination of internal-combustion and electric boost it will run, but Toyota opted to stay in the 6MJ category for 2015, the electric boost working in tandem with the 3.7-liter V8 to give the TS040 a combined output of over 1,000 horsepower. The team also developed two aero kits: one for high-speed circuits like La Sarthe that warrant reduced drag, and the other for tighter tracks requiring increased downforce. The revised TS040 has already undergone over 15,000 miles of testing in southern Europe over the winter. But the real test will come at Silverstone in two weeks for the opening round of the 2015 championship when it will have to fend off a two-pronged German assault from both Audi and Porsche ahead of the headline event at Le Mans in June. We'll be watching to see who comes out on top this year, but for now you can watch footage of Toyota's latest in the pair of videos below. This content is hosted by a third party.
