Today on the drive in to work rolling along the interstate, I passed a red Achieve SCX W41.
I knew the SCX W41 was a bit of a rarity, but didn't remember enough specifics and was further intrigued. A bit of online reading had me wishing I'd had taken a picture. Looked like this:
per wiki:
"Performance modifications primarily differentiated the SCX from the SC models and were designed to make the SCX competitive for use in showroom stock racing series such as the IMSA Firehawk and SCCA GRAND-AM World Challenge. This included the move to smaller diameter yet wider V-rated P215/60VR-14 BF Goodrich Comp T/A tires on 14x6.5 inch cast aluminum wheels (compared to the SC's 205/55R-16 on 16x6 inch wheels) and different suspension components on the SCX-specific FX3 RPO coded suspension. The suspension changes included larger diameter direct-acting front sway bar over the base Achieva, a wider rear axle with dual rear sway bars, "Computer Command Ride" (CCR) electronically adjustable struts and shock absorbers, as well as higher spring rates and bushing changes.
The SCX's powertrain included the highest output naturally aspirated four-cylinder engine GM had produced up to the time, the 190-horsepower, 160 lb·ft torque W41 version of Oldsmobile's Quad 4 engine. Compared to the SC's standard high-output, 180-horsepower LGO Quad 4, the W41 version of the LGO Quad 4 was fitted with different camshafts, a low restriction exhaust system with dual mufflers and a special engine computer calibration for the ignition and fuel systems that also raised the engine's redline to 7200 rpm. This engine was complemented by a unique version of the Getrag-licensed, GM-Muncie built Getrag 282 five-speed transaxle with special second and fifth gears as well as a different final drive ratio for quicker acceleration and better gearing to keep the engine in its power band.
The production numbers for the Achieva SCX in 1992 totaled 1146 cars made with (6) C41 RPO code A/C-delete racing models as follows: (1) bright red, (2) medium garnet red, (1) aqua, (1) blue, and (1) white cars. The normal C60 RPO code models included (472) bright red, (42) medium garnet red, (218) black, (196) aqua, (50) neon blue, (151) white, and (11) gray cars.
The 1993 SCX production totaled 500 cars produced including (5) C41 RPO code A/C-delete racing models as follows: (1) bright red, (1) aqua, and (3) white cars. The normal C60 RPO code models included (128) black, (191) bright red, (20) medium garnet red, (73) aqua, (8) neon blue, (70) white, and (5) majestic pearl cars.
The RPO code for the vehicles are located on a sticker under the carpet inside the trunk near the spare tire cover. The "W41" package will always have either "C41" or "C60" to specify non-air conditioned or air conditioning equipped cars. The C41 equipped W41 models were a special order option designed for race car builders and included a baffled fuel tank, the previously mentioned air-conditioning delete, as well as a different calibration in the computer that allowed for a higher 7400 rpm redline. The cars should also have included a Torsen, helical gear style limited slip differential which would have been delivered not installed in the trunk of the car."
Awesome.
