Infiniti is planning a product upgrade for the 2013 model year.

Nissan's Infiniti luxury brand is preparing to rollout a freshened model line next year, including the division's first-ever electric car. Following the market launch of its seven-passenger JX crossover this year, Infiniti will debut updated versions of its G and M sedans in 2013, along with the brand's first electric car, the Nissan Leaf-based LE. As confirmed earlier this year, Infiniti will launch an updated version of its popular G sedan during the spring of 2013. The next G is expected to switch to a Mercedes-Benz-sourced rear-wheel drive platform and also adopt a version of the German automaker's turbocharged four-cylinder gas engine. A V6 will remain on offer, and Infiniti is reportedly considering using a turbocharged V6 for its performance-minded IPL model. A coupe version of the G sedan will likely bow later in 2013 or early in 2014. Following the launch of the new G sedan, Infiniti will debut a revised version of its M sedan. The M was substantially upgraded for the 2011 model year, so the four door's 2014 refresh should be relatively minor. Expect subtle styling tweaks both inside and out, but the car's powertrains should carryover largely unchanged. Infiniti's long-awaited Leaf-based electric car will launch later in 2013 as a 2014 model, according to Automotive News. Called the LE, the compact electric will borrow most of its styling cues from the LE concept car that debuted at the New York auto show. The LE will boast an electric range of 100 miles, besting the Leaf's 74 mile rating. Look for Infiniti's 2014 lineup to begin appearing as early as this November's Los Angeles auto show.
