Today, Tesla starts selling the Model X in Australia. It's a $130,000-plus all-electric SUV that seats up to seven adults in comfort, can travel nearly 550km on a single charge, and can accelerate up to 100km/h in just over 3 seconds. Like the Model S, you can charge it for free at Tesla's network of Superchargers.

Where the Model S was based around a relatively simple concept, though -- a luxurious car built around a huge battery and electric motors -- the Model X integrates that technology into every door and panel. It's one of the most complicated cars you can buy, and you'll start seeing it on Australian roads soon.
