2012 Camaro V-6 ups the ante with the new LFX 3.6 liter V-6

by DrivingEnthusiast

Chevrolet has announced details of it’s heavily revised V-6 engine for the 2012 Camaro. The Camaro arrives in the fall of 2011 and includes suspension changes and much-needed interior ergonomic improvements.  

According to Chevrolet, the new engine, dubbed “LFX”, features:

  • New cylinder head design with integrated exhaust manifold
  • Improved intake port design and larger intake valves within the cylinder heads
  • Longer-duration intake camshafts
  • Composite intake manifold
  • New fuel pump and isolated fuel rail
  • New, optimized-flow fuel injectors
  • Structural front cover and cylinder block enhancements
  • Stronger and lighter-weight connecting rods
  • Camshaft cap and throttle body design enhancements.

Integrating the exhaust manifold into the cylinder head is a technology whihc is becoming much more common over the past few years. The benefit is purely emissions. Hobbyists won’t be able to install an aftermarket header onto this design, but very likely the exhaust flow is so optimized that it wouldn’t be of much value anyway.

Chevrolet emphasizes in their press release the importance of direct injection. Horsepower is rated at 323 – compare that to Ford’s port-injected 3.7 liter engine with only 305 (what was leading edge a year ago is falling behind as more technology is applied). Torque is an extremely healthy 278 lb-ft. Very clearly Chevrolet, like Ford, understands that the driving characteristics of the base engine greatly add to the desirability of the car.  And the sales figures for the Camaro, besting the Mustang, clearly demonstrate this.

A new generation V-8 engine family is coming too, although it won’t be available in 2012. All of the same technologies seen in this V-6 will be applied to an all-new 5.5 liter V-8 engine that will provide equal or better power and much improved emissions and mileage. The biggest problem for the Camaro, however, remains the shear size of the car. Solving that problem wil have to wait a few years for the arrival of an all-new and much lighter chassis. As a driving enthusiast, it’s very difficult to get very excited about the current car due to it’s size and bulk, but the next generation Camaro arriving in the in 2014-2015 timeframe will see advanced technology applied to the design of thchassis.

2012 Camaro: 45th Anniversary Edition Boosts Power, Comfort

Sports car brings new, more powerful V-6, sport suspension and new technologies

2011-04-13

DETROIT – Chevrolet Camaro, America’s most popular sports car, extends its momentum with enhancements for the 2012 model year. Highlights include an improved version of its standard 3.6L direct injection V-6 engine, a new FE4 performance suspension package for SS coupes and several interior and technology improvements, such as a revised instrument panel design, new steering wheel and rear camera system.

The enhancements arrive in time for Camaro’s 45thbirthday, which will be celebrated with this summer’s release of the 45th Anniversary Special Edition Camaro. Continuing the tradition of Camaro anniversary models, the 45thAnniversary Special Edition carries all the upgrades for 2012, with additional unique design elements, inside and out. 

“The appeal of Camaro design and performance has powered it to the top of its segment,” said Rick Scheidt, vice president of Chevrolet marketing. “For 2012, we’re capitalizing on that momentum with enhancements to Camaro’s performance and comfort.”

Also coming in early 2012 is the high-performance Camaro ZL1, the most technologically advanced car ever developed in its segment.

Class-leading 3.6L V-6 engine

Camaro’snew 3.6L direct injection V-6 – the LFX engine – goes into production this summer. It delivers an SAE-certified 323 horsepower (241 kW) at 6,800 rpm – an increase of 11 horsepower (8 kW) over the 2011 engine, with no compromise in fuel economy.

The LFX delivers the most standard power in the regular sports car segment. It is also 20.5 pounds (9.3 kg) lighter than its predecessor, which promotes a more balanced driving experience. EPA-estimated highway fuel economy for the ’12 Camaro is 30 mpg (2LS model).

Compared to the 3.6L V-6 in 2011 models, the new LFX engine features:

  • New cylinder head design with integrated exhaust manifold
  • Improved intake port design and larger intake valves within the cylinder heads
  • Longer-duration intake camshafts
  • Composite intake manifold
  • New fuel pump and isolated fuel rail
  • New, optimized-flow fuel injectors
  • Structural front cover and cylinder block enhancements
  • Stronger and lighter-weight connecting rods
  • Camshaft cap and throttle body design enhancements.

Direct injection is the key technology enabling the engine’s combination of power and efficiency. It optimizes fuel delivery to the combustion chamber by introducing fuel closer to the combustion chamber. The result is better efficiency in the combustion process leading to increased fuel efficiency at part and full throttle. It also uses a new fuel pump for the direct injection system, along with a new, isolated fuel rail. The new fuel pump is quieter, while the isolated fuel rail further reduces fuel system noise.

FE4 suspension enhances performance

The new FE4 suspension debuts as a performance improvement for the Camaro SS coupe in 2012, focusing on more refined handling.

“Our objective was to create a more precise sport suspension for the SS coupe, with greater road-holding capability,” said Al Oppenheiser, Camaro chief engineer. ”We applied lessons learned from extensive track testing to better refine the suspension geometry for flatter cornering, a more neutral balance during hard turns, and minimized understeer at the limit.”

Elements of the FE4 package include:

  • Retuned front and rear dampers
  • New solid front (23 mm) and rear (24 mm) stabilizer bars
  • Twenty-inch aluminum wheels and P245/45R20 front/P275/40R20 rear tires (SS).

More than just new components, the new FE4 performance suspension incorporates learning from the ongoing development of the high-performance Camaro ZL1. In particular, the suspension geometry has been adjusted, including reshaped stabilizer bars that are repositioned outboard of the shock mounts. This results in more effective body control and more precise response in performance driving.

Interior, exterior and technology updates

The 2012 model year brings appearance, ergonomic and technology upgrades inside for Camarodrivers and passengers. The interior updates include a revised instrument panel appearance, with new instrument graphics and trim, as well as a new steering wheel design and a power lift feature for the front passenger seat. The steering wheel features a fresh new look and ergonomic improvements intended to support performance driving.

Also new for Camaro in 2012 is a Rear Vision Package, which adds a rearview camera system and an auto-dimming mirror to the existing Rear Park Assist feature. The rearviewcamera system complements the rear parking assist by providing a video display of the area behind the car, with the video image appearing in the car’s inside rearview mirror.

On the exterior for 2012, a new rear spoiler will be added as a standard feature for Camaro; and the taillamps that had been a part of the RS appearance package option are also being made standard. Additionally, a new, body-color “sharkfin” antenna joins the RS package.

Crystal Red Tintcoat replaces Red Jewel as an exterior color.

45th Anniversary package details

Launching this summer, the 45thAnniversary Special Edition commemorates both Camaro’s lineage and its 21st-century revival. Camaro fans will get their first look at the 45th Anniversary Special Edition at the Camaro5 Fest II, April 15 in Arizona. The anniversary package will be offered on Camaro’stop two trim levels (2LT and 2SS) for both coupe and convertible body styles.

The exterior signature of the 45th Anniversary Special Edition is its unique rally stripe, in red and silver, that contrasts the Carbon Flash Metallic paint. The package also includes:

  • Unique 45th Anniversary hood and deck stripes; badges located beneath the front fender emblems
  • New-design 20-inch wheels in dark silver
  • Fog lamp and taillamp bezels finished in dark silver
  • RS-style taillamp lenses
  • Standard rear spoiler and HID headlamps
  • Body-color roof molding
  • Jet Black interior with leather-trimmed seats featuring the 45th Anniversary logo
  • White instrument panel and door trim inserts with the 45th Anniversary logo on the instrument panel
  • Red, white and blue stitching on the seats, steering wheel, shift knob/boot, door armrests and console lid
  • 45th Anniversary logo on the steering wheel and sill plates.
