The second-generation Nissan Leaf is a significant improvement over its predecessor, but its paltry 150-mile range leaves a lot to be desired compared to its competitors such as the Tesla Model 3 and Chevrolet Volt. Luckily, Nissan is developing a longer-range model called the "E-Plus," which will launch as a 2019 model.

The automaker has announced an all-new model will debut at CES in Las Vegas next month, which will likely be the new long-range Leaf since the model was originally supposed to be unveiled at the 2018 LA Auto Show but was delayed after fired chairman Carlos Ghosn's arrest.

The long-range Nissan Leaf is expected to get a larger 60 kWh battery that will deliver over 225 miles of range, which would make the car a lot more competitive with the Chevrolet Bolt and Kia Niro EV that can travel more than 230 miles on a single charge. The bigger battery will also allow for a more powerful motor that will increase the output from 140 hp to around 200 hp.

As well as potentially unveiling the new long-range Leaf, Nissan will show the Leaf Nismo RC race car at the event as well as an "EV café," so expect electric vehicles to feature prominently at Nissan's stand. In addition, Nissan will show the IMx Kuro concept, and give demonstrations about Nissan Energy "including solutions that create a fully integrated electric vehicle ecosystem." The automaker will also introduce a new technology that will let people "see the invisible", which sounds like it could be related to driver assist systems. Nissan says this technology will create "an entirely new driving experience through connected worlds."
