"Camaro 1LE Concept

Born in the Camaro’s third generation and refined further in the fourth generation as a road-racing performance package, the legendary 1LE option code designation returns to the Camaro as a concept intended to carve up road courses. While only a concept, it borrows production components from both the Camaro SS and forthcoming Camaro ZL1 to deliver a competition-ready package. Hash mark graphics on the front fender are pure Chevrolet racing cues, too.

Vehicle highlights:

- Victory Red exterior color, with flat black hood and hash mark extensions
- Satin black splitter, rocker panels, rear spoiler and outside mirrors
- Sport suspension featuring Magnetic Ride Control
- Electric power steering
- Six-speed manual close-ratio transmission
- Lightweight 20x10-inch (front) and 20x11-inch (rear) racing wheels (satin black)
- Goodyear® Eagle F1 Supercar G asymmetrical tires (from the ZL1)
- Brembo® six-piston front calipers, with two-piece front rotors, and four-piston rear calipers (Chevrolet Official Licensed Product)
- Dual exhaust outlets with ZL1-style active exhaust and diffuser
- Shock tower brace
- Chevrolet Accessories red engine cover
- Black leather interior with Light Stone stitching
- Graphite Silver door and instrument panel inserts
- ZL1 shifter with Light Stone stitching
- ZL1 flat-bottom steering wheel
- Chevrolet Accessories pedal kit


“The Camaro 1LE concept is all about the track,” said Al Oppenheiser, chief engineer for the Camaro. “It’s an all-out race car package that pays tribute to that special option from the past.”"

Not to be negative Nancy, but does the magnetic ride control add weight and how does it actually work for handling compared to a decent typical adjustable shock? The 1LE was known to be an as stripped down factory Camaro as possible with some performance benefits. I am glad they are sticking with the same SS engine. I know how the car world works though.. not likely to see a 1LE made purposely the same way as the 4th gen

All I see is a bunch of opinions about ride quality there. I could probably search but I don't really have time. I'm more interested in how well it works in higher performance applications compared to a well setup typical shock and spring setup.

^ Gotta wait a little bit, since the MRC 3 comes out on the ZL1 first, which isn't even out yet till early 2012...

Here's what GM says in their ZL1 Dealer Reference Guide:

"Magnetic Ride Control™ (MRC)
The Camaro ZL1 will feature the third-generation of Magnetic Ride
Control (MRC). MRC employs valveless damping and Magneto-
Rheological (MR) fluid technology. MR fluid is a suspension of
iron particles in a synthetic fluid. When the system is activated,
the particles are magnetized and aligned into fibrous structures,
changing flow resistance. By controlling the current to an
electromagnetic coil inside the piston of the damper, the system
varies the suspension firmness to match the road and driving
conditions. The new design allows even more precise control of
the electrical current (and magnetic flux), allowing greater range
between the softest setting for ride comfort and the firmest setting
for track driving. The new dual-coil design also enables faster
response, with damping levels now adjusted up to 1,000 times per
second – about one adjustment per inch of vehicle travel at 60 mph
– making the system exceptionally responsive to changing driving
and road conditions. There are three settings for MRC in the ZL1:
Tour, Sport, and Track.


Performance Track Management (PTM )
Exclusive to GM and first introduced on the Corvette ZR1, PTM
is a feature that tailors the performance of ZL1 to match the
driver’s skills and driving conditions. This advanced system
integrates Magnetic Ride Control, launch control, Traction
Control and stability control. Five PTM performance levels or
modes are available:
■■Mode 1 – Traction Control set for wet conditions, with stability
control on and Magnetic Ride Control set on Tour
■■Mode 2 – Traction Control set for dry conditions, with stability
control on and Magnetic Ride Control set on Tour
■■Mode 3 – Traction Control set on Sport 1, with stability control on
and Magnetic Ride Control set on Sport
■■Mode 4 – Traction Control set on Sport 2, with stability control
off and Magnetic Ride Control set on Sport
■■Mode 5 – Traction Control set on Race, with stability control off
and Magnetic Ride Control set on Track


Brembo® Brakes
ZL1 is equipped with a significantly larger, extremely robust,
Brembo brake system that’s considered world-class (6-piston front
vs. 4-piston on SS). Brembo is a renowned high-performance brake
system manufacturer and leading supplier to Formula™ race teams.
Brembo brakes provide fade resistance and are designed to stand
up to repeated high-speed stops.


Electrically Assisted Steering (EAS )
Electrically Assisted Steering is an innovative power-assist system
connection between the ZL1 steering system and the engine. The
assist power is applied directly to the rack with a belt drive and
a ball nut mechanism. This design allows for lower inertia, lower
friction and more direct steering feel, as well as superior response."

Ironhead

Bryan, the mag shocks are heavier. Iron infused fluid, electromagnets.... there's almost no way they couldn't heavier than a "normal" shock.

As to how they perform, that seems to be hit or miss. Likely this is because, like any normal factory shock, it's still up to the engineers to spec the calibration on the thing.

They seem to have good reports on some cars like the CTS-V. On other cars (like the Z07 Corvette), not so much.

The first gen models also used to overheat under hard usage IIRC. Shouldn't be a surprise really when you consider how they work. Not sure if that's still the case on these later gens.

What all problems do they have with Z07 spec'd cars? Do they have problems on F55 cars or the ZR1's?

I want to be inside that car. More so then Jessica Alba!

Damn Sexy if you ask me.

Ironhead

I tried looking for it but I can't remember where I read it (I get just about every single car magazine out there delivered to the house but I only keep GRM) but I've seen reviewers complaining about the mag shock Z06s bounding around too much on bumpy / undulating back roads.

The same source praised the V series cars and the Ferrari 458 so I don't believe there was any built in bias against the technology.

I dunno about SIK02SS' questions, but here's some detail off the ZL1, which the 1LE shares some (but not all) downforce enhancements with...

GM's press release on ZL1 aerodynamics:

Firmly Planted: Camaro ZL1 Designed for Downforce

DETROIT – With supercar levels of performance and technology, the 580-horsepower (432-kW) Camaro ZL1 can reach 170 mph (273 km/h) on the famed Nürburgring’s Nordschleife course in Germany. To maintain stability and steering response at that speed, the ZL1 features an aerodynamic design that generates downforce to press the tires against the track.

“The Camaro ZL1 lapped the Nürburgring in an incredible 7:41.27 seconds, which would not have been possible without work of our aerodynamics team,” said Al Oppenheiser, Camaro chief engineer. “The design of the ZL1 creates downforce like a race car, harnessing air pressure to press the tires against the track for extra grip and control at high speeds.”

Most production cars are designed with some lift at speed slip through the air for improved fuel economy. The Camaro LS and Camaro SS are no exceptions, enabling the Camaro LS to deliver 323 horsepower (241 kW) and up to 30 mpg on the highway.

Design for high-speed track capability takes in other considerations.

For the ZL1 – the fastest Camaro ever – the aerodynamics team set out to generate downforce for improved handing at speed while minimizing the amount of increased drag that could reduce fuel economy and the vehicle’s top speed. With the computer-assisted design recommendations, engineers tested full-scale clay models and full-size prototypes in the General Motors’ wind tunnel – shaping clay and trimming foam board by hand to affect changes and measure them immediately.

Outside of the aerodynamics laboratory, engineers tested the ZL1’s aero aids on GM’s Milford Road Course, other race tracks and the unique “rolling road” wind tunnel at the Auto Research Center in Indianapolis.

When the dust settled and the wind-tunnel blades came to a stop, the Camaro ZL1 produced 65 pounds of downforce at an equivalent 150 mph (241 km/h) – compared to 200 pounds of lift in a Camaro SS – which was offset by an increase of only 40 counts of additional aerodynamic drag.

“From the driver’s seat, the added downforce makes a huge change in the feel, and responsiveness of the ZL1 at high speeds,” said Oppenheiser. “One of the best examples of how aerodynamics improved the performance of the ZL1 is the ‘Fuchsröhre,’ or Foxhole at the Nürburgring. In the ZL1, you can take that sweeping left-hand corner flat-out in fifth gear – nearly 160 mph (257 km/h). That’s a great testament to the confidence-inspiring stability and control the aerodynamic design helps give the Camaro ZL1.”

Seven elements contribute to the downforce of the ZL1:

1. Front fascia – The front fascia channels air for engine and brake cooling. The lower opening is larger than in a Camaro SS, providing greater airflow to the engine’s intercooler heat exchanger. Even the grille “fins” were shaped for optimal airflow. The corners of the front fascia, too, were reshaped to minimize lift, while the brake-cooling ducts in the outer corners of the lower grille opening provide a direct, high-flow path to the brake rotors. Cooling the brakes helps extend their life, particularly n the race track.

2. Hood – The ZL1’s hood has a vented, carbon fiber insert, contributing to both engine cooling and aerodynamic downforce. With traditional sealed hoods, air trapped in the engine bay creates lift at the front axle. With the ZL1, the specially shaped vents draw air up through the engine bay – allowing a significant volume of air flow while keeping the front tires firmly connected to the pavement.

3. Front splitter – Instead of a traditional front air dam, the ZL1 incorporates a racing-style splitter to help create downforce. Unlike some competitors’ vehicles that come with an add-on splitter, the ZL1’s does not have to be installed at the track – it is installed at the factory, and is designed with enough ground clearance for all driving conditions.

4. Front tire deflectors – The deflectors push airflow around the rotating wheels and tires more efficiently, reducing lift and drag. And by using deflectors in place of a traditional air dam, the downforce is less sensitive to pitch changes, making the ZL1 feel more stable at high speeds.

5. Belly pans – The ZL1 has two of them: one beneath the engine cradle and one at the rear of the engine assembly, just in front of the transmission. Both extend the width of the chassis out to the wheelhouse opening, to minimize airflow turbulence under the car. NACA-style ducts are incorporated into the rear belly pan for transmission cooling.

6. Rocker panels – Although subtle in appearance, the carefully shaped rocker panels help reduce lift and drag, while also contributing to stability during high cross winds. They also provide stone protection with the ZL1’s wider tires.

7. Rear spoiler – One of the most dramatic aero enhancements comes with the ZL1’s rear spoiler, which contributes approximately 150 pounds of down force at the cost of only 1 count of drag. It is taller and wider than the Camaro SS spoiler and incorporates the center high-mounted stop lamp.

The Camaro ZL1 goes on sale later in 2012. A convertible model will also be offered for the 2013 model year, starting in the summer of 2012. Pricing will be announced later.
