The best Honda can do?

Honda’s introduce the CR-Z hybrid 2+2 coupe. Car & Driver calls it a spiritual successor to the popular CR-X sports car from the eighties and nineties, and the Insight a few years back. I don’t buy it, especially considering how different the three cars are.

It’s not a bad looking car, but it’s nothing to marvel at either.

What really makes me wonder is the fuel economy. It’s estimated at 7.6 litres/100 km city and 6.4 litres/100 km highway (31 mpg city/37 mpg highway). This is from a gasoline/electric hybrid system with a combined output of 122 bhp and 128 lb-ft of torque. What the horsepower figure means depends on the car’s weight, but the torque is looking good. The best thing I see about the CR-Z is that it comes with a 6-speed manual transmission.

As a point of comparison, let’s go back to the 1989 Honda CR-X. When it was introduced in 1983, it you could choose between a 1.3 litre or 1.5 litre engine. Later, a more efficient 1.5 litre engine replaced the 1.3, and the model was called the CR-X HF, for high fuel economy.

The 1989 Honda CR-X HF had an EPA fuel economy rating of 5.7 litres/100 km city and 4.7 litres/100 km highway (41 mpg city/50 mpg highway). Remember that this is 1989. It’s certainly no gasoline/electric hybrid. It didn’t even require premium gas.

Part of the reason the CR-X is so efficient is that it’s a two-seater, allowing it to be smaller and carry less mass. Another factor is that the CR-X HF delivered only 62 hp. The current gasoline-powered Smart ForTwo does better with 70 hp, but the CR-X HF would be more fun to drive with its 90 lb-ft of torque versus the Smart’s 68 lb-ft.

At first, I was astonished that the CR-X HF was 32% more efficient than the coming CR-Z, but I can see the compromises they made are responsible for the disparity. Yes, stricter emission and safety standards play a part, but they decided to double the number of people it can carry and double the power. Certainly that’s going to have an effect on the fuel economy, hybrid or not.
