Here’s another point in the discussion of making green cars fun vs. making fun cars green. Best Motoring put together this track battle around a rain-soaked Tsukuba circuit after Honda released the CR-Z in Japan. The two main cars to pay attention to are the Tec-Arts Eco AE86 and the Modulo Sports CR-Z. The Tec-Arts Eco AE86 has been modified to improve its gas mileage. The alternator and the starter were updated to modern units and the power steering was converted from hydraulic to electric assist all in the name of reducing parasitic drag on the engine. Reflective window tint was also installed to reduce the need of the air conditioning. The Modulo Sports CR-Z is a factory trim package that was available only in Japan. It comes with sport springs, dampers, brake pads and Advan Neova AD08 tires. Watch the video to see how they did. The race starts at 3:30 after the introduction of the cars.
