In the next two to three years, Tesla will expand beyond the current Model S sedan to include a sport utility vehicle called the Model X and a lower-priced Model III passenger car. However The Sleuth sees that some sleeping giants will come gunning for Tesla with their own all-electric models. Audi will soon launch the mid-engine Audi R8 e-tron sports car and has also earmarked the e-tron Quattro wagon concept for production. As well, Porsche says the 800-volt Mission E concept that can blast to 60 mph from zero in 3.5 seconds is also bound for production. Lastly, a Taiwan-based start-up has developed the Thunder Power Sedan that has a 400-mile range and can be recharged to nearly 50 percent of its battery capacity in 30 minutes. Undoubtedly there will be more such electrics to follow.
