Just days after GM might have slightly cannibalized Volt sales for the next couple months by announcing a tweaked battery and other updates
due in August, a GM insider reportedly revealed that a 2.0-liter turbo
engine will be introduced by summer 2013 for the 2014 model year.
Since their launch, the extended-range electric Volt and
Opel/Vauxhall Ampera siblings have relied on an 83-horsepower 1.4-liter
generator mated to electric propulsion for a combined 149 horsepower,
273-pound-feet torque. But word has it that present four cylinder is
“definitely not” going to make it to 2014, according to an anonymous
source speaking to Jay Cole (aka Statik) for Inside EVs.
The 1.4 was reportedly always considered a compromise pressed into
service at a time of limited/frozen budgets when GM was undergoing
restructuring. If the info is correct, the now better-funded company
will select for the gasoline portion of the powertrain something closer
in specification to the 260-horsepower, 2.0-liter (GM-sourced) Ecotec
turbo engine Fisker uses in the Karma.
The actual 2.0-liter Ecotec turbo said to be pending for the Volt –
currently rated at between 220-270 horsepower – has “been thoroughly
vetted” and “will most likely” be the 2014 replacement, said Inside EVs.
This more-potent powerplant would possibly also call for an upgraded
electric motor and the improved gas-electric powertrain would also be
used in the pending Cadillac ELR which GM has said will rely on the
Volt’s powertrain, and is positioned as a sleek, high-line corporate
halo.
The speculation about the electric motor was by Inside EVs,
and otherwise no news from the insider was reported as to possible
updates to the 2014 Volt’s battery pack, or what should be specifically
expected regarding range, or other performance parameters from the more
powerful powertrain.
In any event, since it has also been leaked that the Cadillac ELR will launch in 2014,
updating the Volt’s powertrain for that year would make all the more
sense to fit with the sporty image portrayed by the extended-range Caddy
that would compete with Fisker’s six-figure extended-range Karma.
While it was noted GM engineers had always wanted a purpose-built
generator, the 2.0-liter Ecotec believed to be in the most-favored
status at the moment will be used in the pending Buick Verano that rides
on the same Delta II platform that the Volt does. Inside EVs
quoted GM Global Chief engineer for Ecotec engines, Mike Anderson, who
praised the engine that already sees duty in the Buick Regal GS.
“Our continuously variable valve timing is tuned to work in tandem
with direct injection and twin scroll turbocharging to achieve optimum
fuel economy, lower emissions, and instant performance when needed,” he
said. “Having 295 pound-feet (400 Nm) of torque available over a wide
range of engine speeds makes for a very exciting driving experience.”
Of course, if utilized the in the Volt, Opel/Vauxhall Ampera siblings, and ELR, the 2.0 Ecotec Turbo engine that was awarded by WardsAuto
as one its “10 Best Engines,” would be mated with an electric motor and
tuned for use as a generator. It nonetheless promises to spice up
performance, or it could be optimized to help extend range, or offer a
combination of both.
As would be expected, GM refused to confirm or deny truth of the news
leak of the 2014 engine, citing the usual policy of not commenting on
future product, so this is officially a rumor until further notice.
