(from Chevrolet Press
Release) Corvette Marks 60 Years of Performance with 427
DETROIT – Chevrolet today unveiled the 2013 Corvette 427 Convertible
Collector Edition – the fastest, most capable convertible in
Corvette’s history – as well as a 60th Anniversary Package that will
be available on all 2013 Corvette models.
“The 2013 model year will be historic for Corvette, marking its 60th
Anniversary and the final year for the current ‘C6’ generation,”
said Chris Perry, vice president, Global Marketing and Strategy for
Chevrolet. “We couldn’t think of a more fitting way to celebrate
these milestones than bringing back one of the most-coveted
combinations in the brand’s history – the Corvette convertible and a
427 cubic-inch engine.”
The 60th Anniversary Package and 427 Convertible will make their
public debut at the Barrett Jackson collector car auction in
Scottsdale, Ariz., on Jan 21, and will arrive at U.S. Chevrolet
dealers early this summer.
Corvette 427 Convertible Collector
The Corvette 427
Convertible blends elements of the Z06 and ZR1 models to create the
fastest and most-capable convertible in Corvette’s history.
Its heart is the 427-cubic-inch (7.0L) LS7 engine from the Corvette
Z06. Rated at 505 horsepower (377 kW) and 470 lb.-ft. of torque (637
Nm), it is the most powerful engine ever installed in a production
Corvette convertible – and, like the Z06, the 427 Convertible is
only available with a six-speed manual transmission.
The LS7 was co-developed with the Corvette Le Mans-winning GT1
engine and features lightweight titanium connecting rods and intake
valves, as well as racing-inspired high-flow cylinder heads and a
dry-sump oiling system. It is assembled by hand at GM’s Performance
Build Center, where customers who purchase the 427 Convertible
Collector Edition can purchase the Corvette Build Experience option
and assemble the engine that will power their new car.
Supporting performance elements in the Corvette 427 Convertible
include the driveline and rear axle system from the Corvette Z06, a
rear-mounted battery and standard Magnetic Selective Ride Control.
The standard 19-inch front and 20-inch rear wheels are wrapped in
ZR1-style Michelin PS2 tires. Lightweight machine-face Cup wheels –
introduced on the 2012 Corvette Z06 with Z07 and Corvette ZR1 with
PDE performance packages – come standard and include unique
gray-painted pockets. Black Cup wheels or chrome ZR1-style wheels
are also available.
The 427 Convertible also features several carbon-fiber components
that help reduce weight, including:
• Carbon fiber
raised hood (introduced on the 2011 Z06 Carbon Edition)
• Carbon fiber Z06-style fenders
• Carbon fiber floor panels
• The “CFZ” carbon fiber front splitter and rocker panels are
optional on the 427 Convertible, and included with the 60th
The weight reduction
brings the 427 Convertible’s curb weight to 3,355 pounds (1,522 kg).
Combined with its 505-horsepower LS7 engine, it gives the 427
Convertible a power-to-weight ratio of 6.64 – or one horsepower for
every 6.64 pounds of vehicle mass. That’s better than:
Porsche 911 Turbo S Cabriolet – 6.90
• Audi R8 5.2 RSI Spyder – 7.58
• Aston Martin DBS Volante Convertible – 7.82
• Ferrari California Convertible – 8.31
The combination of low
mass and high output will make the 427 Convertible one of the
fastest convertibles in the world, delivering estimated 0-60
performance of 3.8 seconds, quarter-mile performance of 11.8
seconds, lateral acceleration of 1.04 g and a top speed of more than
The 427 Convertible is available in 2LT, 3LT and 4LT trim levels and
will carry a unique vehicle identification number sequence, similar
to the Corvette ZR1.
Corvette 60th Anniversary Package
All 2013 Corvette
models, including the 427 Convertible, will be available with a 60th
Anniversary Package, featuring an Arctic White exterior with a Blue
Diamond leather-wrapped interior with suede accents. Convertible
models will have a blue top.
Additional content includes a ZR1-style rear spoiler, special
badging, gray-painted brake calipers and the “60th” logo on the
wheel center caps, steering wheel and seat headrests. An optional
graphics package adds full-length racing stripes in Pearl Silver
Blue, including a tonal stripe stitched into the convertible top,
extending the graphic theme over the roof.
For 2013, all Corvettes will feature 60th Anniversary badges on the
fascias and the “waterfall” panel on convertible models, as well as
60th logos in the instrument panel gauge cluster and on the sill
Charity Auction at Barrett-Jackson
The first Corvette 427
Convertible offered to the public will go to the highest bidder at
the Barrett-Jackson Scottsdale collector car auction, on Saturday,
Jan. 21. Proceeds from the sale will benefit the Drive to End Hunger
food relief program.
Chevrolet and Hendrick Motorsports are teaming up for the auction,
including Hendrick team driver and four-time NASCAR Sprint Cup
Champion Jeff Gordon. Team owner Rick Hendrick helped launch the
Drive to End Hunger program with AARP and the AARP Foundation.
The Drive to End Hunger is part of a multi-year sponsorship for
Gordon’s No. 24 Chevrolet. It calls on racing fans, corporations and
charitable organizations to raise money, build awareness, and engage
Americans who face the threat of hunger.
A legacy of 427-powered Corvettes
Corvettes, particularly convertibles, offered from 1966 to 1969 are
some of the most-coveted and collectable Corvettes ever produced.
The first 427-powered Corvette rolled off the assembly line for the
1966 model year. Two performance levels of the 427 were initially
offered – an “L30” version rated at 390 horsepower and the “L72,”
which cranked out 425 horsepower. Both were rated at 460 lb-ft. of
The range of 427 engines grew in 1967, with the addition of the
“L71” and “L88” options. The L71 added a unique triple-carburetor
induction system that helped boost output to 435 horsepower. Known
to collectors as “427/435” cars, these ’67 models – especially the
convertibles – are especially sought-after collector cars.
The “L88” delivered 430-horsepower (with a single four-barrel
carburetor) thanks to racing-tuned aluminum heads. Intended for
customers who would immediately transform their new Corvette into a
race car, the L88 was installed in just 216 production Corvettes
between 1967 and 1969.
In 1969, a special “L89” 427 engine combined the L71’s induction
system with the L88’s aluminum heads, offering maximum horsepower
with an approximately 100-pound weight advantage over the standard
iron heads. Also in 1969, Chevrolet built two “ZL1” 427 Corvette
coupes. The ZL1 engine was essentially an all-aluminum version of
the L88, with the aluminum cylinder block and heads offering a
tremendous weight advantage for racing. More of the engines were
sold as crate engines to racers.
By 1970, the big-block engine grew to 454 cubic inches, just as the
trend in high-compression, high-performance engines was beginning to
wane. The four-year run of 427 Corvettes was already established as
the golden era of performance
Commemorative Collector Edition
and Anniversary Edition models
Rare and low-production
examples of the Corvette have been around since its 1953
introduction, but Chevrolet didn’t begin building commemorative
models until 1978, when the 25th Anniversary model – also known as
the Silver Anniversary Corvette – was offered. The Corvette was in
its third generation then and at the close of that epoch in 1982, a
Collectors Edition was offered, as well.
Those special models launched what has become a tradition for the
Chevrolet Corvette, which has offered milestone anniversary and
generational collector-edition models ever since. The 2013 Corvette
427 Convertible represents the first time a Collector Edition and
Anniversary Edition are being offered in the same year – and
available on the same car.
