Though the Model Y shares a platform with its Model 3 showroom stablemate, it's around 10% longer - 4,750mm in length. And of course, being an SUV, it's a hatch, not a saloon. Getting in and out via the pillarless doors is easier because of the taller body. And Tesla has designed the car to be able to incorporate an optional 3rd seating row too, though the occupants had better not be above school age. As usual with the brands cars, you open the car with your smartphone - there's no physical key - but if it's run out of battery, you get a credit card-sized key as well, just in case.
Inside, differences over the Model 3 saloon are few, the dash and interior of that car carried over almost completely. You can have a bigger panoramic glass roof - that's the only real difference. So, as usual on a Tesla, the fascia is dominated by a huge central infotainment touchscreen of upright portrait format. Build quality and material richness might not be quite what you're looking for if you're seeking a premium branded model in this sector but it's quite comparable with a volume maker rival. As usual with a Tesla, there are almost no physical buttons in the cabin - almost everything's controlled via the touchscreen, which is sharp to look at and as easy to use as ever. The back seat is comfortable for a couple of adults. And there's a decently-sized boot, extendable to 1,869-litres in size if you fold the rear seats. You also get a bit of extra space under the bonnet.
