Arrow Direct Injection V8 Camaro/ Hybrid Camaro

ModernCamaro.com
September 22, 2009

Could we see a DI V8 and/or a Hybrid Camaro soon?



In a recent press release from Tom Stephens (Group Vice President, GM Powertrain Europe) He speaks about Corvette's Future. "To boost fuel economy, GM plans to reduce the Corvette's weight, offer tires with less rolling resistance and offer an engine with direct injection, variable valve timing and cylinder deactivation. Electric power steering alone could add about 0.5 mpg." says Stephens. Revealing that Corvette has a DI V8 on the way with the new generation. What does this mean for Camaro? Could Camaro get the DI V8 from the Corvette? Along with that, Stephens also states that a hybrid Corvette is not out of the question if fuel standards require it. "We will only do a hybrid if that is what is required to maintain the vehicle, I think we have a pretty good plan right now that probably will not require a hybrid in the near term." Says Stephens. With Camaro production much higher than Corvette, could this indicate that a hybrid Camaro could not be far off?

With direct injection, fuel is sprayed directly into the engine cylinder, where it is mixed with air. As the fuel vaporizes in the cylinder, the air and fuel mixture is cooled. This enables the use of a higher compression ratio, which improves engine efficiency and performance.

See how Direct Injection works: Video


GM tested there experimental engine based on their current all-aluminum Gen IV 6.2L V-8 (L92) rated between 380-403 hp in stock form. When they added DI the prototype V-8 produced “well north of 450 hp (on gasoline),” says Dave Sczomak, development engineer-GM Powertrain Advanced Engineering. Sczomak also says adding E85 ethanol makes even more power because of its higher octane rating(106 octane). Besides the increase in HP, DI aslo added about 10% in low-end torque and 3-6% improvement in fuel economy to the 6.2L V8.

The US has pushed CAFE standards for fleetwide average of 35.5 miles per gallon by 2016, which is four years ahead of the schedule

The application of direct injection also reduces cold-start hydrocarbon emissions by 25 percent.

GM is probably pushing to move the whole fleet to DI where possible. We should see it on the v8s in a couple years. Hopefully sooner.

They were talking about it before the CAFE bull-crap was announced...then they fell silent about it until recently.

I agree. They already stated that there will be no more GEN IV engines. GEN V engines will have DI on them. It's just a matter of time. I am sure they will be going into their trucks as well.

I am 99.9% sure that if the Camaro is around that the Camaro will have DI V8s well before 2016. If this was an article from Motor Trend, they would just say "Camaro will have DI V8" with nothing from GM to back it up. That's why I just posed the question instead, but the question is when? How many years will the current engine be good for? What about the competition? Will Ford up the Mustang HP? Will Ford be able to do that and still meet CAFE?

Another question is, will they keep the 6.2L or just match or slightly increase HP from current model and Lower displacement?

Another thing is hybrid. If GM says it will have a hybrid Corvette if they have to because they will do anything just to keep the Corvette, does GM have the same commitment to the Camaro?

The new DOHC 4-valve engine appears from spy photos to feature dual variable valve timing which helps put power at or above the 400 mark. That means both intake and exhaust cams can be individually timed for optimum settings in all conditions. It might have direct injection for future applications, but prototype photos appear to show standard port injection. There have been news accounts however of the engine being tested with direct injection and turbo charging, but the first show of the new 5.0 will be naturally aspirated.

If the 2011 Mustang keeps its weight atvantage over the Camaro, then if Camaro doesn't do something, the Mustang will have a huge atvantage.

A turbocharged, direct-injected V8 can make 550hp without trying.
Lose the turbo and 500hp is still possible with a little effort.

That said, I do think displacements and power levels will be limited at least at first, since the current focus would have to be fuel economy, thanks to CAFE.
