Electric drivetrain aside, the Tesla Roadster isn't the most practical sports car on the market. Like its Lotus counterpart, the Roadster is lacking space for both passengers and parcel, something Tesla CEO Elon Musk is all-too-happy to admit. But as you'd expect from the plucky upstart and its confident chief executive, Tesla has big plans to expand beyond the Roadster and Model S sedan, and it's got the Porsche 911 in its sights.
Although we've known for some time that Tesla plans to base future models on the Model S platform – ranging from a base model to a full-fledged GT – the automaker's been tight-lipped about the specifics of future sports cars. However, Musk let it slip during an interview that a 911 Turbo shares a space in his garage with a Roadster, and he loves its ability to schlep the kiddies to school in its diminutive back seats. Inspired, Musk said that the next Tesla sports car would be a 2+2, boasting 10% more room for rear-seat passengers and 50% more trunk space than the 911, along with all-wheel drive. Additionally, the Model S' flat architecture means that styling won't be completely influenced by the drivetrain, allowing for "greater functionality with avant garde, aggressive" styling. Although this new coupe's future is largely dependent on the success of the Model S, if Tesla can keep the lights on and continue R&D, we might see the GT as early as 2012 or 2013.
