Getting inside the Model X can be quite a theatrical event. The front doors may be conventional but are electrically powered, with the driver’s door opening automatically when you unlock the car with the key fob. Step inside and a press of the brake pedal will see the doors close behind you.
It’s the rear doors that are the more interesting, though. Although they look like they’d be impossible to open in a confined space, the doors are double-hinged (one on the roof and another above the window line) so they can open with as little as 11 inches of clearance outwards. There are also ultrasonic sensors that lie beneath the bodywork so you can't open one into an immovable object.
When open, they offer excellent access to the rear seats, while parents will be able to strap their offspring in without banging their head on a doorframe. What may irritate is the time it takes to open and close a door. Who knew that a new Tesla would have something in common with a Peugeot 1007?
Still, they do offer exceptionally easy access to the middle row of seats, be it two or three individual chairs. Press a button and the seats move forwards and tilt to help you get into the rearmost row. An adult will fit back there, but most will need the centre row pushed forwards a fair bit. Taller individuals will also feel their head touch the rear screen.
Once you’ve selected Drive on the Mercedes-sourced column shifter, the Tesla creeps forward quietly, if not silently.
Left in Normal mode, it gathers speed rapidly, even with four people in the car. Switch to Insane (or Ludicrous where fitted) mode and you can certainly believe the 3.8sec it takes to get to 60mph from rest. It really is quick enough for there to be no sane reason to opt for the Ludicrous Speed upgrade.
What's always impressive with electric cars is the smooth way in which they gain speed. With only one gear ratio, acceleration is completely linear, although it does tail off noticeably at higher speeds.
Under normal driving conditions, the Tesla proves easy to drive, although rearward visibility isn’t great. The huge windscreen may look good, but there’s a lot of reflection coming from the dashboard in direct sunlight. Surprisingly, though, the tinted panoramic roof does protect well, even against direct sunlight.
One thing that might take some getting used to is the regenerative brakes. They slow the Model X like you're pressing the brake pedal when you simply come off the throttle. You soon get used to this, partially because it tops up the batteries and partially because you can drive for 90% of the time without moving your foot from the accelerator.
Even when the optional air suspension is fitted, you won’t find a wafty ride in any of the modes. The Model X is composed at all speeds but with a firm edge that could become jiggly on UK roads.
