GM released data on two new engines.

2.4L DI details
The new 2.4L DI engine delivers an estimated 180 horsepower (134 kW) @ 6700 rpm and 172 lb.-ft. of torque (232 Nm) @4900 rpm. It uses technology based on GM's other four-cylinder direct injection applications, but with unique features designed for its specific application. This includes an 11.4:1 compression ratio that helps build power, slightly dished pistons that increase combustion efficiency and injectors with an application-specific flow rate.

GM benchmarked the best fuel system and noise attenuation products to provide customers with quiet operation.

3.0L DI details
The new 3.0L DI engine is a variant of GM's family of high-feature DOHC V-6 engines that also includes GM's 3.6L DI engine in the Cadillac CTS – an engine named to Ward's AutoWorld's 2009 "Ten Best Engines" list for North America, for the second consecutive year.

The 3.0L is rated at an estimated 255 horsepower (187 kW) and 214 lb.-ft. of torque (290 Nm), for an impressive power-to-displacement ratio of 85 hp per liter. (Output will vary by model.) The 3.0L DI features an isolated fuel injector system that reduces the direct injection high-pressure fuel system pulses for quieter operation. Rubber isolators are used with the fuel rail to eliminate metal-to-metal contact that would otherwise transmit noise and vibration from the high-pressure fuel system.

Along with direct injection technology, both the 3.0L DI and 2.4L DI engines use variable valve timing to optimize power and fuel efficiency across the rpm band, as well as reduce emissions.

So will I beat both of them?

Anyway, it is good info about new engine.

Try neither of them?

From wikipedia article on 3100 engine: "Power was 170 hp-175 hp and torque was 190 ft·lbf–195 ft·lbf."

lol I guess not.

Palsut the 3.0 is to make 255hp. That's more then the L67. Torque on the other hand...

That's why I don't know lot of engine stuff.

Since my engine is 3100 so I thought 2.4 or 3.0 is slower than mine. At least I pass Toyota Prius today. lol

Sweet i passed my friends 05 subaru Wrx Sti today then he gave it gas and he passed lol

Bigger isn't alway better.

For example my 5700 is rated at 250 hp. But the torque is well over 300.

LOL

a true accomplishment, Palsut. Was it parked?

Dude, that was cold-blooded... lmfao

that can't be right, the older grand prix gen is faster than the turbo prix, and 1 second slower than a gtp from 97???

16-25 mpg? Everything else says 18-28, and 18 is what I get when I "hot rod" it.

Sounds like the 2 new engines are a winner.

hahaha it was on traffic light stop.
