2007 Hyundai Azera: gets 56.1 miles per gallon
March 20, 2007
The little-known "marsupial hybrid" can net tremendous gains in fuel economy. In the Azera, this was achieved by keeping the engine in a minimally consumptive mode and by slashing aerodynamic drag, rolling resistance and heat losses for a large portion of a 404.1 mile trip.
Actually, we needed ballast for an upcoming towing test. It needed to be easily portable, narrow enough to fit inside the 8.5 x 39' trailer yet usefully heavy.
The Azera's 3,840 lb turned out to be shaped just right. As a bonus, it's nose-heaviness allowed us to place the weight closer to the trailer's axles, minimizing the effect on tongue weight.
If you're thinking that a trailer that big plus an entire Hyundai equates to a lot of weight, you're right. Stay tuned for a full test of our marsupial hybrid's front end.
