C6 · 2005–2013

C6 Options & RPO Codes

The C6 order sheet built three different cars from one platform: the 400-hp LS2 tourer, the 505-hp hand-built Z06, and the supercharged ZR1 — the fastest Corvette yet sold. Every code in the 2005 production table is anchored here, along with the generation's defining codes from later years; the 2006–13 option tables are still being added to their year pages.

Engines

LS2 — the 6.0-liter, 400 hp

The C6's launch engine, 2005–07: the LS family grown to six liters and a round 400 hp — the first base Corvette to reach that number. Standard equipment on the sheet; everything else orbited it.

LS7 — the Z06's 7.0-liter

2006–13, exclusive to the Z06: a hand-assembled 427 cubic inches — the magic number of the big-block era in small-block form — with titanium rods, dry-sump oiling, and 505 hp at a 7,000-rpm redline. One of the great naturally aspirated American engines.

LS3 — the 6.2-liter

2008–13: the base engine's mid-cycle upgrade — 6.2 liters, 430 hp (436 with the NPP exhaust), and the block that would carry Chevrolet performance for a decade.

LS9 — the ZR1's supercharged 6.2

2009–13, exclusive to the ZR1: an Eaton-supercharged, hand-built 6.2 making 638 hp — the most powerful engine GM had ever put in a production car, pushing the Corvette past 200 mph.

Models & packages

Z06 — the aluminum-frame monster

2006–13: no longer just an option group but a distinct car — aluminum frame, wider body, the LS7, and fixed-roof rigidity, at a price that embarrassed cars costing twice as much. The C5 formula, escalated.

ZR1 — the Blue Devil

2009–13: carbon-fiber bodywork, the LS9, carbon-ceramic brakes, and a polycarbonate window in the hood so you could see the supercharger. The third car to wear the code — after 1970 and 1990 — and the first to crack 200 mph from the factory.

Grand Sport — the widebody LS3

2010–13: the Z06's wide body and brakes around the LS3 — the sweet spot of the late C6 range, wearing the 1963 lightweights' name.

Z51 — Performance Package

$1,495 in 2005: bigger brakes, stiffer springs and bars, shorter gears — the closest a base coupe got to Z06 manners, continuing the code's long run.

NPP — dual-mode exhaust

From 2008: vacuum-actuated exhaust flaps that open under load — quiet leaving the neighborhood, loud when it matters, and worth six extra horsepower on the LS3. One of the C6's signature latter-day options.

Suspension & brakes

F55 — Magnetic Selective Ride Control

$1,695: the magnetorheological dampers continued from the late C5 — not available with Z51 in 2005, later central to the ZR1's ability to be both daily driver and 200-mph car.

FE1 / FE3 — suspension calibrations

Soft ride base (FE1) and the sport calibration (FE3) — the standard menu.

J55 — heavy-duty brakes

The uprated brake line item, a code in service since the C4.

Transmissions & axle

MM6 / MZ6 — the 6-speed manuals

The Tremec six-speed — base calibration (MM6) or the closer-ratio version bundled with Z51 (MZ6).

MX0 — automatic with overdrive

The four-speed automatic at launch — replaced mid-generation by the six-speed paddle-shift automatic that finally ended the Corvette automatic's apology era.

The axle codes

2.73 standard with the automatic (GU2), 3.42 with the manual (GU6), and the 3.15 performance ratio for $395 (G90).

Wheels

QG6 / QG7 / QX1 — wheel finishes

Painted aluminum standard (QG6), polished for $1,295 (QG7), or gray-painted (QX1) — same five-spoke, three moods.

Roof & body

CC3 / CF7 — roof panels

The transparent targa panel at $750 (CC3) or body-color (CF7) — the glass-top lineage unbroken since 1978.

CM7 — power folding convertible top

$1,995: the C6 convertible's party trick — the first power top on a Corvette since 1962.

Interior & electronics

AQ9 / AR9 — seats

The reclining buckets, domestic (AQ9) and European-spec (AR9).

AAB — Memory Package

Driver presets, carried over from the C5.

UV6 — Head-Up Display

The windshield projection, now with track modes — a C5 pioneer feature matured.

UE1 — OnStar

$696 in 2005: the telematics era arrives on the order sheet.

URB / US8 / US9 — audio

The audio ladder: single-CD radio (US8), the multi-disc changer (US9), and the $1,400 Bose premium system with DVD navigation (URB) — the first factory nav in a Corvette.

N37 — power telescoping column

Power telescope, manual tilt — the long-serving code's C6 tour.

Emissions & export

FE9 — federal emissions

The 50-state baseline certification.

CV3 / MAE / Z49 — export codes

Mexico (CV3), the rest of the world (MAE), and the perennial Canadian bundle (Z49).
