2006 Chevrolet Monte Carlo SS: the LS4 arrives

This record's own dek states that the SS gets a 5.3-liter V8 with Displacement on Demand for 2006, rated 303 hp, with 8,794 SS coupes built per Wikipedia, the Displacement on Demand system itself a fuel-saving cylinder-deactivation feature built into the LS4. Wikipedia's own 2000-2007 production table, citing The Encyclopedia of American Cars, gives 32,567 Monte Carlos of all trims for the year, but this record's own production note flags that Wikipedia itself gives no citation for the separate 8,794-car SS figure, so that number is carried as reported without a named underlying source behind it.¹

Two engine entries describe the same LS4 5.3-liter V8 with Displacement on Demand: the factory specification sheet gives 303 hp at 5,600 rpm and 323 lb-ft at 4,400 rpm without stating the SAE basis, while the separate restoration kit calls the same figures SAE certified but marks them as estimated values on the page itself, a tension this record carries as two attributed sources rather than resolving to one authoritative rating for whether the number is a firm certification or a rounded estimate. The LS4 runs 10:1 compression with premium fuel recommended but not required, paired with the Hydra-Matic 4T65-E automatic as the sole transmission documented for the SS.

This record's own transmissions section is empty for 2006 despite a documented gear-ratio set for that same 4T65-E: 2.92, 1.56, 1.00 and 0.70 in first through fourth with 2.38 in reverse, all drawn from the restoration kit's own chassis and drivetrain table. A 3.29:1 final drive ratio is recorded alongside a separately labeled 2.93:1 overall drive ratio, two figures under two different headings that this record keeps distinct rather than treating as duplicates of the same number.

Five exterior colors are documented, Laser Blue Metallic, Victory Red, Black, Silverstone Metallic and White, with this record's own paint note stating that none of them is footnoted as unavailable on the SS specifically, though that silence is not the same as a stated confirmation that all five were SS options. This record's own prices, options and interiors sections are all empty for the year, with no dealer-order price, RPO list, or upholstery detail found in an accessible source for the SS.

Specification detail includes 18-inch machined aluminum wheels, an FE3 suspension with a hollow 34 mm front stabilizer bar, dual-rate rear coil springs and a hollow 19.4 mm rear stabilizer bar, 2.3 steering turns lock-to-lock, a 40-foot curb-to-curb turning circle, P235/50R18 W-rated Goodyear Eagle RS-A tires mounted on 18x7 machined-face or polished aluminum wheels, an 18/28 mpg EPA city/highway rating, and a 3.78-by-3.62-inch bore and stroke for the LS4.

This record's own performance and identification sections are both empty for the year, and no conflict or unpublished lead is logged despite the two separate factory documents this record draws on for engine and chassis detail throughout 2006. No period road-test figure or VIN-decoding detail was located in an accessible source, leaving production, engine, drivetrain, paint and dimensional specification as the whole of this record's coverage for the year.
