The tenth-generation Impala was updated for the 2014 model year, with sales and production launched March 4, 2013[ It is the first American sedan in 20 years to earn Consumer Reports’ top score, with a score of 95 of a possible 100 points
This new version, which was introduced at the New York Auto show in April 2012, is larger and more upscale than the existing model (sharing the extended Epsilon II FWD platform with the Cadillac XTS) to reduce price overlap between Impala and Malibu, similar to how the Ford Taurus and Ford Fusion are positioned in Ford's lineup. The current versions are being assembled in Oshawa, Ontario, Canada, alongside the ninth-generation Impala (now renamed the fleet and rental exclusive-only Impala Limited), and at the Detroit/Hamtramck Assembly in the U.S. All cars will feature a six-speed automatic transmission with sport and manual shifting modes.
On April 4, 2012, General Motors released a public media article covering the 2014 Chevrolet Impala at the New York International Auto Show. The new Impala is described by General Motors as "a reestablishment of a popular, enduring and iconic nameplate with a new outlook on style, comfort, efficiency, and safety". A new exterior and interior emphasizes Chevrolet's new design direction, and features a more fluid structure with sweeping body contours and a much-improved, flush, and flowing interior according to GM.
The tenth generation models were shipped to dealerships across North America on March 25, 2013, and officially went on sale to the public April 1, 2013. That same day regular production on the Impala (the 2.4L eAssist and 3.6L equipped versions/LT2 and LTZ2 trims only) began at their Oshawa plant, while production at GM's Detroit-Hamtramck plant (the 2.5L equipped versions/LS, LT1 and LTZ1 trims) started production on April 8 and arrived to dealerships in May. The eAssist versions will go on sale in the fourth quarter of 2013.
