Like the original 1958 edition, the 2008 Impala 50th Anniversary Edition is distinguished with unique trim and amenities.

“Chevrolet is thrilled to mark 50 years of the Impala,” said Ed Peper, Chevrolet general manager. “Few brands can claim such a heritage and throughout the decades, Impala has always stood for the value, performance and style that has made Chevrolet America’s car.”

The Impala 50th Anniversary Edition goes on sale across America in mid-2008. It is based on the popular and well-equipped Impala LT, with the following unique and standard features:

• FE3 Sport Suspension (replaces the FE1 Touring Suspension)
• Four-wheel ABS
• Eighteen-inch alloy wheels (replaces 16-inch wheels)
• Rear spoiler
• “50th Anniversary” Impala badge on the C-pillar
• Two-tone, leather-trimmed seats and “50th” logo embroidered on the front head restraints
• Eight-way power-adjustable driver seat (replaces six-way adjustability)
• Leather-wrapped steering wheel with accent-colour thread (includes audio controls)
• Ebony carpet
• Ebony floor mats with accent threading
• “50th” Anniversary emblem on the sill plates
• Two premium exterior colours: Black Granite Metallic or Red Jewel Tintcoat

The 50th Anniversary Impala also includes a one-year upgrade to the OnStar Directions and Connections package, including Turn-by-Turn Navigation.

Also standard is the Impala’s convenient flip-and-fold rear seats, the cushions of which flip forward to reveal a storage tub that serves as a covered storage area beneath the seat and offers convenient grocery bag hooks. A generous pass-through from the boot can be made by flipping the seat bottoms forward and the seat backs flat – an exclusive feature in the mid-size segment.

The 50th Anniversary Impala is powered by a refined and efficient 3.5 litre V-6, rated at 211 horsepower (157 kW)* and 214 lb.-ft. (290 Nm)* of torque. Vehicles with federal emissions systems in the United States are equipped with the 3.5 litre engine, which is compatible with E85 ethanol fuel, allowing the vehicle to run on any combination of petrol and/or E85.

Impala history

Introduced in 1958 as a premium package for the full-size Bel Air, the Impala was an immediate sales success, selling approximately 60,000 units. It was designated a stand-alone model in 1959 and offered top-of-the-line amenities and performance, including a 335-horsepower (250 kW), 348-cubic-inch (5.7 litre) V-8 engine. Sales increased to approximately 175,000.

As Chevrolet’s full-size platform evolved throughout the 1960s, so did the Impala. The model range included coupes (hardtops), sedans and convertibles – with early-year models distinguished by their six-taillamp rear styling. Other full-size Chevy models had only four taillamp lenses.

In 1961, the performance-oriented Impala SS was introduced. Today, it is considered by many to be one of the first true 'muscle cars', with power coming from a variety of standard and optional engines, including a 409-inch V-8 that produced one horsepower per cubic inch. Only 142 units of the 409-powered SS models were built that inaugural year, but 409-powered Impalas would go on to be scourge of drag strips across America and be the subject of a popular song by The Beach Boys, when the American entertainers sang the hit tune known simply as "409".

For 1965, the full-size platform was redesigned and the Impala was all-new. Customers responded to the sleek, new design with enthusiasm. More than 1 million Impalas were sold that model year, setting a sales record that has since gone unmatched.

New-generation Impalas were introduced in 1971 and 1977, with the ’77 models featuring “downsized” styling that still offered full-size accommodation, but with more compact and efficient exterior dimensions. The re-sized Impalas carried the brand into the mid-1980s, when the name was changed to Caprice.

The Impala returned in 1994 as the high-performance Impala SS – a sinister-looking 'muscle car' built with the heavy-duty powertrain and suspension components of the Caprice police car package. It was a sell-out success for three consecutive model years, bowing out only with the end of production of GM’s full-size rear-drive platform.

After a three-year hiatus, the Impala name returned again for 2000 on Chevy’s full-size, front-drive architecture. That seventh-generation Impala proved popular, but greater success came with the refined eighth-generation model, which was introduced for 2006.

Sales jumped nearly 18 percent in 2006, reaching nearly 290,000 units. Sales increased again in 2007, up more than 11 per cent through November and challenging the sales rate of key competitors such as the Honda Accord.
