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.

Here's my preface before I start; I am American, I love my country and I have a great appreciation for our American made products.With that being said, Toyota has had their hands in direct injection and turbocharging and PERFECTED it LOOOOOONG before the American OEM's. Google the 1jz-fse and you'll find that Toyota had direct injection perfected prior to the year 2000. They also had turbocharging PERFECTED starting in 1987 with the Supra. For what it's worth, Toyota had a perfect functioning turbo vehicle with ZERO reliability issues prior to the year 2000. I beg you to entertain the idea of finding another company that has done this. The JZ platform is arguably the most reliable and boost friendly platform out there. In any event,don't think for a minute that Toyota has just jumped on the band wagon - they have been there and done that.

You talk about research, yet clearly you have done none. Toyota deserves about 10% of the credit in the turbocharging department. First of all, GM was the first to turbocharge a production engine, with an Oldsmobile and the infamous Corvair in '62. Secondly, nothing is ever perfected, and turbos were a huge 80's fad. GM had a turbo Buick Regal in '84 and several twin-turbo Trans-AM mules were in the works in '93 at Pontiac. The Buick GNX from '87 was faster than 'vettes from a decade later.
And let's don't even talk about Porsche and the other Germans. But there was a gas price slump in the mid-late '90s, and the fad wore off. Turbos add cost at several places, maintenance and insurance being two key ones.
