General Motors has announced a new lineup of Ecotec engines that will
power its smaller offerings through the end of the decade.

DETROIT A new generation of Ecotec small-displacement engines
streamlines General Motors' global powertrain portfolio with a modular
architecture that broadens its adaptability to global markets and
reduces manufacturing complexity while offering customers
leading-edge efficiency, refinement and durability.
The new engines were developed for GM's global vehicle portfolio and
will power many of the company's highest-volume small cars and compact
crossovers including the next-generation Chevrolet Cruze
specifically tailored for China, which launches in 2014 as a 2015
By 2017, more than 2.5 million new Ecotec engines are projected to be
built annually in at least five manufacturing locations around the
globe: Flint, Mich. (U.S.); Shenyang, China; Szentgotthárd, Hungary;
Toluca, Mexico; and Changwon, South Korea. The Flint facility alone
represents an investment of more than $200 million in technology and
tooling to support the engines' production.
"Transportation solutions vary around the world and GM is
committed to developing engines matched to the needs of the regions
where they're sold," said Steve Kiefer, GM vice president, Global
Powertrain Engineering. "The new engine family is designed to
achieve segment-leading refinement and efficiency, and will make its
way into five GM brands and 27 models by the 2017 model year."
The new Ecotec portfolio will include 11 engines, with three- and
four-cylinder variants ranging from 1.0L to 1.5L including
turbocharged versions and power ratings ranging from 75 horsepower
(56 kW) to 165 horsepower (123 kW), and torque ranging from 70 lb-ft
(95 Nm) to 184 lb-ft (250 Nm). The architecture is also designed to
support hybrid propulsion systems and alternative fuels.
The first production applications include a 1.0L turbocharged
three-cylinder for the Opel ADAM in Europe, and 1.4L turbocharged and
1.5L naturally aspirated four-cylinder engines for the 2015
next-generation Chevrolet Cruze in China.
The turbocharged variants enable the engines to deliver the power and
torque of larger-displacement engines with the efficiency of smaller
engines. For example, the turbocharged 1.0L three-cylinder used in the
Opel ADAM makes as much power as the naturally aspirated 1.6L
four-cylinder it replaces with an estimated 20-percent improvement
In fact, the new Ecotec family is on the leading edge of efficiency,
with the new 1.4L turbo up to five percent more efficient than the
1.4L turbo engine it will replace. The new Ecotec engines also deliver
segment-challenging refinement. Noise intensity is up to 50-percent
quieter than Volkswagen's EA211 1.4L four-cylinder and up to
25-percent quieter than Ford's 1.0L turbo three-cylinder.
The new Ecotec engines represent a clean-sheet design and engineering
process, leveraging the diverse experience of GM's global resources.
Technologies such as central direct fuel injection, continuously
variable valve timing, turbocharging and variable intake manifold
airflow help achieve efficiency goals with broad power bands, for an
optimal balance of strong performance and lower fuel consumption.
"The new Ecotec architecture represents the most advanced and
efficient family of small-car gas engines in GM's history," said
Tom Sutter, global chief engineer. "Along with performance and
efficiency targets, we've also aimed for segment-leading refinement
with low noise and vibration and we've hit the bulls-eye."
Modularity in parts such as four-cylinder and three-cylinder blocks
that share bore spacing, bore diameter, liners and other dimensions,
reduces complexity while increasing the flexibility to quickly adapt
the architecture for new applications.
The new Ecotec engines are calibrated to run on regular unleaded gas
even the high-output turbo variants.
The new 1.4L turbo for the 2015 next-generation Chevrolet Cruze in
China is estimated at 148 horsepower (110 kW) and 173 lb-ft of torque
(235 Nm). The 1.5L is rated at an estimated 113 horsepower (84 kW) and
108 lb-ft of torque (146 Nm).
In China, Cruze models with the 1.4L turbo engine will also feature an
all-new dual-clutch gearbox.
