Porsche said to be working on sporty model for 2019 Germany’s Porsche AG is reportedly working on an electric car to debut in 2019, joining a growing list of companies that seem intent on challenging Tesla Motors Inc. for a chunk of the electric-car market. Apple Inc. AAPL, +2.71% is also secretly working on an electric car, The Wall Street Journal has reported. Google Inc. GOOG, -1.31% has said it is working on a driverless, fully electric car. But neither appear to be designing a car that could compete with the flair of a TeslaTSLA, -4.50% The Apple car could resemble a minivan, the Journal said. Andprototypes of Google’s self-driving cars show a small, rounded car that are far from the models that have made Porsche synonymous with ultra-luxurious muscle cars. Porsche’s all-electric offering will be a “sporty” four-door, four-seater ground-hugging car more compact than the Panamera, Porsche’s luxury four-door sedan, according to Car magazine. The company, part of Volkswagen AG VOW3, -0.02%aims for a driving range of more than 300 miles between charges, the magazine said. That is slightly more than a top-of-the-line Tesla now offers. The magazine doesn’t mention how much the car might cost. Porsche already offers hybrids such as the Panamera S E-Hybrid, which starts at $96,000, and it also has rolled out hybrid racing cars. This, should it materialize, would be its first purely electric offering. Porsche representatives in the U.S. didn't immediately return requests for comment. Another competitor in the electric-car market is Nissan Motor Co.’s 7201, -0.04%NSANY, +0.34% Leaf, which has a far more affordable starting price of around $29,000. Nissan sold 30,200 Leafs in 2014, 34% more than in 2013, and 1,070 last month. Tesla doesn’t disclose monthly sales, but two estimates say it outsold the Leaf in January. A third puts Tesla sales for the month just behind the Leaf. Tesla is launching two new models in the next few years. This summer, it expects to start selling its Model X, an electric SUV. It plans on offering the Model 3, a mass-market electric car that would sell for $35,000 to $40,000, in the next two to three years. Its Model S luxury sedan, on the road since 2012, starts at $70,000 for a base model. A top-of-the-line Model S has a driving range of 270 miles between charges. Claudia Assis
