There are some features on the IS 300h which sound great in theory but in practice can be frustratingly fiddly.
Take, for example, the electrostatic switches to control the interior temperature, which are a new feature on the IS.
Instead of turning a dial or pressing a button to set the interior temperature, you swipe your finger along a metal strip.
It’s a neat idea but like the eight-way joystick control (see http://www.fleetnews.co.uk/cars/reviews/lexus/is/executive-2013/is-300h-25-se/49333/page/4/), there’s a certain knack to using it.
I can’t help thinking that the electrostatic switches are just being clever for the sake of it.
The keyless entry, known as the ‘Smart entry and start system’, is more useful, however.
There is no need to press a button to unlock the car. You just need the key in your pocket or handbag for the doors to unlock. It’s a blessing when it’s pouring with rain and you don’t have to hunt around for your car keys.
To lock the car you simply touch an indentation on the door handle.
This type of keyless entry is still pretty rare, although it can be found on superminis, like the Nissan Micra, not just premium models.
Besides appreciating the keyless entry system, I’ve continued to enjoy just how quiet the IS 300h is, particularly on motorways.
Aerodynamics help cut wind noise around the A-pillar and mirrors. Lexus also uses sound-absorbing materials in the cabin.
A few longer journeys recently have meant that fuel economy has improved marginally this month, up from 47.1mpg to 47.8mpg.
