Lastly, the biggest change in the interior is the instrument panel. The speedometer is styled like a sports chrono watch. The large needle showing the speed, the smaller 3 used for volts, temp and oil. There is also a gauge used for fuel consumption. Want to guess what other car with a 3 in it's number has one.
All gauges are well placed and easy to read.
Even with the funky chrono layout, one gets used to the dash easily. Naturally, leather covers the seating surfaces. On driving the IS, the ride is firm with out being overly stiff. You get to keep all your fillings after a test ride. As with most sport sedans, the IS allows more noise into the cabin than with any other Lexus.
