Few may not think of Toyota as falling behind in fuel-efficient
engines thanks to the company’s dominance in hybrid powertrains, but the
Japanese automaker’s non-hybrid engine tech is now years behind its
competition. As it continues to refresh its global portfolio, Toyota is
hoping to roll out turbocharging, direct injection, and new
transmissions to help eke more efficiency from its internal combustion
engines.
According to Automotive News, Toyota will introduce a slew
of revised engines and new transmissions over the next two years in
order to catch up with its competition. Toyota has quickly become one of
the few automakers not to take advantage of the efficiency
gains of variable valve timing, direct injection, and turbocharging.
Prominent examples include Ford’s leveraging of much of its lineup on a
number of different downsized, turbocharged engines to replace
large-displacement, naturally-aspirated powerplants, and Mazda’s
Skyactiv suite of technologies that prominently features direct
injection and variable valve timing. The trio of valve timing, direct
injection, and forced induction has become so prevalent that we even named it our 2012 Technology of the Year.
Toyota is hoping to begin rolling out two new engines and two new transmissions starting next year. AN
reports the first of which will be a new 2.5-liter Atkinson-cycle I-4
with direct injection, slated to find its way into the brand’s hybrids.
Coming in 2014 will be a 2.0-liter turbo-four, along with a new
continuously variable transmission for small-to-midsize cars and six- or
eight-speed transmissions for larger vehicles. Currently, only Toyota
hybrids use a CVT and the Lexus LS and IS F are the only models in the
company’s portfolio to use eight-speed automatics. It’s also been
rumored that Toyota may introduce a CVT in the next-generation Corolla to replace the current car’s ancient four-speed auto.
According to our source close to the matter, Toyota originally
planned on introducing a direct-injection V-6 in the 2013 Avalon, but
delayed that to 2015 due to cost. Adding direct injection to current
engines can tack on an extra $128 to the car’s bottom line, says AN.
It was because of this added cost and an incremental increase in fuel
economy that Toyota Motor North America previously passed on direct
injection. The automaker has had direct injection-equipped engines on
sale elsewhere since 2006, and only recently introduced the technology
in the U.S. in the Lexus GS and LS and Scion FR-S.
