2015 Lexus RC F: Throwing Shapes With the Fun Meter
July 7, 2015
Many cars today come with gauges that encourage you to drive in a fuel-conscious manner. The dash on the Nissan Leaf grows trees, while our long-term BMW i3 gives you a letter grade. But our 2015 Lexus RC F has something different, something we're seeing in more new sports cars: A fun meter.
Or at least that's what I call it. "It" is a display that logs peak lateral and longitudinal g-forces. See that little yellow circle? When you accelerate, it moves back. When you brake, it goes forward. When you turn left and right, it does the same. The harder you do these things, the more that yellow circle moves.
The resulting Nurburgring-like shape the circle draws is something engineers call a friction circle (note the abnormally high 1.2-1.3 g-force peak readings either result from banking or electronic optimism). All you need to know is that the bigger the shape, the harder you've driven, and the more fun you've had.
When I'm in the RC F, I see the edges of the circle as a challenge. I think I can make it bigger. Or I might try to draw something with it.
When the circle won't grow any larger, you've logged peak acceleration in every direction. You can call it a high score and hit the reset button.
And then do it all over again.
