2014 Chevy Volt Rumored to Drop 1.4L I-4 for 2.0L Turbo-Four – Should It?

The 2014 Chevrolet Volt may soon see significant powertrain changes. Inside EVs reports that the Volt's 1.4-liter four-banger will be dropped next year in favor of the Buick Verano Turbo's 2.0-liter turbocharged I-4. GM's got many engines in its stable, though – is the turbo-four also found in the Verano Turbo the right choice?

GM's got plenty of suitable powerplants for the Cruze-based Volt. As we see it, there are three engines that make the most sense as a generator for the Volt: the Verano Turbo's 2.0-liter turbo I-4; the Chevy Cruze's 1.4-liter turbo I-4, or the 2013 Cruze's 2.0-liter turbodiesel I-4.

Though the 2.0-liter turbo I-4 is capable of over 250 hp, we think a detuned unit would not only provide a major boost over the Volt's current 1.4-liter I-4, but also be better suited to the upcoming Cadillac ELR, which can sacrifice a little efficiency for added performance.

Perhaps a better option would be a turbocharged version of the engine the Volt already has. The Cruze's 138-hp 1.4-liter turbocharged I-4. This efficient engine would be an easy retrofit under the hood and provide a boost in power up to 138 hp.

The third option is the riskiest, yet many enthusiasts find it the most appealing: the 2013 Cruze's 2.0-liter turbodiesel I-4. Even though diesel sales are rising in the United States, many buyers remain wary of oil burners. A low-revving 2.0-liter turbodiesel would be an efficient way to charge the Volt and likely have a positive impact on fuel economy when not operating on electricity.

If you were to build the 2014 Volt your way, what would you do? Sound off in the comments below.

I would make it a five seater. Lots of families would love to go more green with their vehicles but with limited seating its impossible. One more seat is all I ask!
my Volt lifetime mpg is 110... try that with turbo diesel. The serial hybrid is not a myth, every other diesel train engine is build like one - and for a good rason
Diesel and a gas option. Diesel would give the economy needed.

Admit the price mistake and the electric myth and go with the turbo diesel . Try for 50 mpg hwy. Ha Ha you asked the question and I am reporting my opinion, not that it is shared by Chevy or its confused customers.
Diesel but that won't happen due to CAFE. Putting a Turbo in is just GM rummaging through the parts pin looking for more performance and to try & justify the insane price tag. GM doesn't grasp the concept of correcting a price mistake from day 1.

Best case for everyone? Different choices in powertrain, and maybe even different 'lines', if you will. For example, a 'Sport' line (yeah, laugh if you want) with the 2.0T with some performance and style upgrades, a 1.4T as the every man's line, and the diesel as the efficiency-plus edition. Still, either way, the diesel would be my preferred choice. Oh, but to have choice!

I would have the internal engine run everytime the volt is driven, driving a huge alternator to recharge the Volt's battery.

Go with the Diesel. The gains in economy would be almost immediate.
@Vlad   well you will have to pay to replace that battery pack and their goes your saving!! diesel engines will go 1 million miles + how meny battery packs is that? how far can you go befor recharge? travel as far as you want with the diesel!!
@btc909  they already have it in the 14 cruze!! 46 MPG under  $28,000
