Toyota to Finally Get Onboard With Direct Injection, Turbocharging to Boost Efficiency

Toyota is finally going to catch up to the competition
Toyota is known for producing boring family sedans and SUVs that appeal to a large audience. The company is also known for its fuel efficient
Prius family of hybrid vehicles
. Vehicles like the
manage to achieve 50mpg on the highway thanks to a fuel-sipping gasoline engine backed with a continuously variable transmission (CVT) and an electric motor/battery.
Toyota has largely ignored making significant advances in its traditional gasoline engine/powertrain department; with efficient transmission/engine offerings lagging the competition (the Toyota Corolla still uses a 4-speed automatic transmission when the competition has moved to 6-speed units and CVTs).
However, no longer will its traditional vehicles take a backseat to its hybrids according to Takeshi Uchiyamada, Toyota's product development chief. "By 2015, through improvement in the engine and powertrain alone, we aim to achieve a fuel-efficiency improvement of 10 percent to 20 percent on the models adopting the improvements," said Uchiyamada.
The Toyota Corolla still uses an archaic four-speed automatic transmission and lags behind the competition in fuel economy
Competitors like Ford have already embraced direct injection and turbocharging across much of the produce range (see
), and Toyota is following suit. Toyota plans to introduce a direct injection version of its 2.5-liter four-cylinder engine (this new engine will first see duty in hybrid models). The engine will also find its way into vehicles like the Camry, RAV4, and Venza.
In addition, Toyota will also introduce a 2.0-liter, turbocharged four-cylinder engine that will likely take the place of the 3.5-liter V6 currently found in midsize Toyota sedans and crossovers.
Toyota is also looking to add 6- and 8-speed automatic transmission to its vehicles. This should help vehicles like that aforementioned Corolla with its archaic transmission boost fuel efficiency ratings. The company will also add CVTs to more of its models, a move that has long been championed by Nissan. Nissan provides CVTs in everything from its
tiny Versa subcompact
to the large Pathfinder crossover.
All of these moves largely see Toyota playing catch-up with the rest of the automotive industry. Toyota has for too long placed all of its fuel efficiency eggs in the hybrid basket, while neglecting its bread and butter vehicles. With the competition now fiercer than ever, it now looks as though Toyota has finally realized that not everyone wants to purchase a hybrid in order to get increased fuel efficiency.

First of all, that's no 'beauty about the electric engine', people protest all of those facilities as well. Solar, wind, algae ponds for biofuel, doesn't matter. Environmentalists always find a reason to complain. Don't fool yourself in to thinking there's a magic bullet for them; they touted nat gas for years as a bridge fuel to the future, and once it became actually viable, it's just another fossil fuel anti-christ for them. When a pseudo-religion makes them believe we should return to 5000 BC development-wise, nothing will satisfy them.
As for the general notion you have... Yeah, that's the future, I don't doubt it. Problem is, it's the future. We still live in the present. Battery tech isn't there yet. Quality electric motors are expensive, and many manufacturers are vulnerable to China restricting rare-earth exports. Early studies show potential catastrophe for the grid if EVs were adopted quickly, with a daily crisis when people start coming home from work and all plug in. The systems aren't in place... The systems are barely on the drawing board.
Which is why Keystone is not "stupid," nor is any existing energy project. While those gears are all turning on the future technology, there's no reason to artificially create hardship for ourselves in the interim. Economies are very capable of walking and chewing gum at the same time, even if central planners can not. And specifically for the Keystone, you're a fool if you think that Canada won't find a buyer if not us. They're already working on a pipeline to ship to their west coast, where it'll go to less efficient, dirtier Chinese refineries and get pumped in to Chinese cars with who knows what for emissions controls.
