Interior
The interior layout, fit and finish
One of the reasons the efficiency (and range) of electric cars plummets in cold weather is that lots of energy is used up keeping the interior nice and warm. To help with this, Lexus has fitted small infrared heaters to Premium Plus Pack and Takumi versions of the RZ.
They radiate heat to your legs and those of your front passenger to make you feel as though you’ve got warm blankets on your knees – and they use just 170W. Around 5000W is used if you fire up the main climate control system, so the potential savings are huge. We found we needed the heated seat and steering wheel on as well to stay comfortable without wearing a coat, but even with those working, you’ll be quids in on your energy usage.
