2018 Chevrolet Camaro ZL1 1LE Interior

Chevrolet must have one hell of an overtime budget for its performance-vehicles department. In just the past few years, there have been SSs, Stingrays, 1LEs, Z51s, Z06s, ZR1s, ZL1s, and even V-6 models that have consistently rewritten the bang-for-buck equation. (To say nothing of fellow General Motors brand Cadillac and its immensely talented V models.) Now comes this particular Camaro, one that combines two of those acronyms but wears an invoice price that doesn’t seem adequate to cover the sum of its parts.
Tons of grip, glorious engine sounds, costs far less than it could.
It’s a Camaro, so there’s essentially no back seat, limited visibility, and nowhere to put your phone.
The 2018 Camaro ZL1 1LE stretches the performance envelope like a cruise missile wearing a forty-nine-cent stamp. There’s the Corvette Z06–derived LT4 supercharged 6.2-liter V-8 good for 650 horsepower and 650 lb-ft of torque, the genuine carbon-fiber wing (a first for GM) designed in a Formula 1 wind tunnel that turns into the equivalent of 300 pounds of lead at 150 mph, the gaping front end that swallows 106 cubic feet of air per minute more than a regular ZL1, and the splitter and dive planes. Also, check out the rubber. GM tapped Goodyear and the tiremaker brought its Eagle F1 Supercar 3R to the table: 305/30ZR-19s in the front and 325/30ZR-19 steamrollers at the rear, which is the widest tire ever fitted to a Camaro. Goodyear says they are good for 1.10 g’s of lateral acceleration, but if our well-attuned necks are any gauge, we’re thinking it’s even higher than that. The rubber is wrapped around forged-aluminum wheels one inch smaller in diameter than the regular ZL1’s; along with the tires and compared with the non-1LE car, those rollers save 13 pounds in precious rotating inertia and unsprung mass.

Damper Dan
The other half of the chassis performance comes from Canadian supplier Multimatic in the form of aluminum-bodied spool-valve dampers. Not only do they provide an elegant and passive way to vary damping force, the inverted struts provide a means to achieve race-car-like negative camber at the front end. Via a trick method to switch back and forth between street and track settings, the ball-jointed and forged-aluminum top mounts of the front struts are adjustable to increase negative camber by 1.7 degrees. To set the car to track camber, jack one corner, remove an alignment pin in the wheel well and the three bolts at the top of the strut tower under the matte-black hood, twist the top mount 180 degrees (it has a dual bolt pattern), reattach, and—voilà—instant camber. Combined with fairly common eccentric alignment bolts, the ZL1 1LE can have as much as 3.7 degrees of negative front camber, although Chevy recommends negative 2.7 on the track.
The four dampers together are about 23 pounds lighter than the 2014–2015 Z/28’s steel-bodied dampers. The rear subframe and its multilink suspension are insulated, if you want to call it that, by aluminum pucks, and the rear anti-roll bar is adjustable to three positions. Locking down the rear end and firming up the front communicates every crack in the road and even the slightest variation in lateral thrust with a sniper’s precision.
All of this variability was engineered into the car to allow owners to fine-tune their Camaros to their home tracks. At the Jacques Villeneuve–designed Area 27 in British Columbia, we ran 40-plus laps of the 3.0-mile circuit. It was the brakes—the iron-rotor units carry over from the regular ZL1 except for the ABS calibration—rather than spent tires that prevented us from turning more than five hot laps at a time; the pedal gets a little long on the fifth lap. While we’d like to have seen the 1LE adopt the carbon-ceramic brakes of the Z/28, they’d be costly, and few cars feel as stable while braking in corners as the 1LE. Even when you throw in a downshift, the car never unsettles. The tires claw for grip in corners like a cat scurrying up a tree. Where you expect understeer, you get a neutral balance, and squeezing extra throttle on exit causes the rear end to step out gently—or aggressively if you simply put the hammer down too quickly. We’re quite sure there isn’t a tire made that could contain the LT4’s 650 lb-ft of torque.

When one feels the desire, the car will accelerate in a straight line, too. GM claims the 1LE transformation saves 60 pounds, so we don’t expect the manual-only 1LE to be all that much quicker than the manual-transmission ZL1 coupe we tested. Call it 3.7 seconds to 60 mph and 11.9 in the quarter-mile. The ZL1 automatic will remain the quickest Camaro, despite being roughly 100 pounds heavier than this car.
