Tesla Motors is the leading designer and manufacturer of premium electric vehicles. In 2012, the American automotive company launched the world's first premium electric sedan, Model S. It can accelerate from 0 to 60 mph in about five seconds. The car was named Motor Trend's 2013 Car of the Year and has a five-star safety rating from the U.S. National Highway Traffic Safety Administration.

Late last year, Model S P85D with performance rear motor for supercar acceleration was launched. It was the fastest four-door production car ever made. Another upgrade for P85D was announced last year, with a "Ludicrous Mode," which can go from 0 to 60 mph in 2.8 seconds, per a previous report from Latin Post. 

In the near future, Tesla will also launch Model X, which is a crossover vehicle that started production this year. The car features faster acceleration, falcon wing doors and extra spacing with room for three rows of seating. Tesla has also partnered with Panasonic to produce an affordable mass-market vehicle called Model 3 by 2020.

Not to be outshined, German powerhouse Porsche unveiled a concept car, Mission E, at the Frankfurt Motor Show that combines striking lines with excellent range and performance in one package, as reported by Wired. The concept car is said to be the Tesla-killer and would make the American car company nervous.

In an official announcement by Porsche, Mission E is the first all electrically powered four-seat sports car in the history of the company. The concept car has the design of a Porsche with the first ever 800-volt drive system.

Mission E will have over 600 hp system power and more than 500 kilometers of driving range, with four doors and four single seats. It also boasts all-wheel drive and steering with the capability to accelerate from zero to 100 km in less than 3.5 seconds as well as a remarkable charging time of around 15 minutes to reach 80 percent charge.

The concept car will also be like the classic Porsche sports car that is lightweight with optimal weight distribution and a low center of gravity. The design combines the features of the front end of a Porsche sweepback and is relative to the 918 Spyder and other Porsche race cars.

The dashboard will be divided into two three-dimensional layers that emphasize lightness and clarity. The upper layer shows the driver's display. In between layers is a holographic display that shows individually selectable apps with a three-dimensional effect.

The driver or passenger can use the apps to touch-free control functions such as climate control, contacts, media, navigation and vehicle. It can be activated by gestures that are detected using sensors. For other Mission E features, you can read the full announcement here.
