The new 2014 Chevrolet Impala will target retail buyers while the old model will be aimed at fleets.

General Motors plans to offer two separate versions of the big Chevrolet Impala, both the 2014 remake of the full-size sedan as well as the old model that it was intended to replace.

The previous-generation Chevrolet Impala will remain in production indefinitely and will be aimed strictly at the fleet market while the all-new 2014 will focused on the retail market where Chevy hopes to pick up market share, GM officials said.

Less than one third of the old Impala have been going into consumers’ hands, something that the maker hopes to change with the 2014 model, according to Chris Perry, Chevrolet vice president of marketing. “It’s 30 percent retail, 70 percent fleet right now. We’re going to flip that with the new car,” he said.

The old Impala will serve various fleet buyers, including police departments.

GM has been hoping to significantly boost its retail sales and in some segments is simply walking away from corporate and daily rental markets. Those rentals, in particular, tend to be lower profit and they also tend to have a negative impact on residuals – or trade-in values.

However, GM isn’t giving up on the fleet business for Impala, GM officials said, noting that the size of the sedan makes it an ideal car for fleet customers looking for a full-size vehicle.

Ken Kelzer, chief executive engineer, said GM will continue to build the older version of the Impala exclusively for some fleet customers. “We’ve done this before with some other models,” he noted.

Building more cars on fully depreciated tooling is a financial plus for GM, Kelzer added. “We make money on this car,” he said.

While the market for full-size sedans has shrunk as fuel-prices have climbed, roughly 600,000 full-size passenger cars are sold annually with half the total being purchased by fleet customers.

The chances of confusing potential retail customers is very small because the distribution of the older models will be limited to fleet customers who purchase vehicles in large numbers, Kelzer explained. Retail buyers will not be able to purchase the old model.

Chevrolet is hoping, meanwhile, that it can win over retail customers with the fresh exterior styling, revamped interior and new technology it is offering with the 2014 Impala.

GM now uses three different plants, Oshawa, Detroit-Hamtramck and Fairfax, Kan., to build the Impala as well as other models based on the company’s Epsilon platform, including the Cadillac XTS, Buick LaCrosse and Chevrolet Malibu.
