Chevrolet is making its presence felt at the 2016 Specialty Equipment Market Association (SEMA) Show in Las Vegas, Nevada, by showcasing around 20 unique models, including the styling yet high-tech Chevrolet Chevelle Slammer Concept.
Since the Chevelle Slammer concept is derived from the 1969 Chevelle, it does look similar to this classic car at a glimpse. Chevrolet designer Humberto Ortiz called the 1969 Chevelle as one of the best-looking cars of the muscle car era. For this reason, the carmaker won’t modify its classic cues and proportions.
Wrapped in an all-black exterior, the Chevelle Slammer features a low and raked stance laden with hot-rod attitude. This stance could be altered with a push of a button by an air suspension system, which could lower the ride height to the ground for maximum profiling.
However, Chevrolet modified its chassis to accommodate large 18-inch front and 20-inch rear polished wheels. Moreover, the carmaker made sure the classic lines of the Chevelle remain even though it has revised the body for a smoother custom appearance. Ortiz revealed that the revisions included knocking down the chrome in certain sections and tightening exterior details like its grille and bumpers. In addition, the Chevelle Slammer concept is provided with a Gen Six Camaro-based performance brake system, which includes six-piston front calipers.
The interior of the Chevelle Slammer concept, meanwhile, comes in Adrenaline Red, including its instrument panel, door panels and carpet as well as interior panels, headliner, console and seats. Its seats are derived from a 2016 Camaro while its instrument gauges are compatible with the electronic signals from the Chevrolet Performance engine as well as transmission controllers.
On the other hand, the Chevrolet Chevelle Slammer concept on display at the 2016 SEMA Show is powered by the all-new LT376/535 crate engine mated to a SuperMatic 4L75-E automatic transmission. This new crate engine and gearbox – along with controllers and harnesses -- are part of the Connect & Cruise package from Chevrolet Performance.
Jim Campbell, GM U.S. vice president of Performance Vehicles and Motorsports, called the direct-injected LT376/535 powerplant as one of the most technologically advanced crate engines ever from Chevrolet Performance. While this crate engine is derived from the LT1 engine that powers the Corvette Stingray and Camaro SS, this version comes with a distinct camshaft-and-heads package.
It builds on the Gen V Small-Block family’s technologies and evolves them further while leveraging CNC-ported heads and the high-lift LT1 Hot Cam. Engineers at Chevrolet Performance leveraged the design elements of the LT1 engine’s advanced combustion system to direct air through its optimized cylinder head ports. The camshaft profile allows the new powerplant to build output at higher engine speeds (about 6,800 rpm) while keeping strong torque at low rpm.
Meanwhile, the SuperMatic 4L75-E electronically controlled four-speed automatic transmission features 650 lb.-ft. in torque capacity, making it suitable for several highest-output crate Chevrolet engines.
Since the 4L75-E is more compact than the 4L80 series, it is much easier to install in smaller vehicles. In addition, the new 4L75-E features five-pinion gear sets, a distinct high-strength input housing, heat-treated stator shaft splines, higher capacity servo and induction-hardened turbine shaft, as well as specific valve-body calibration, eight-friction-plate 3-4 clutch and larger 2-4 band.
