Where a C-class motor from Estes puts out the equivalent of 2 pounds of thrust for one second, an H-class motor--the entry point to high-power rocketry--puts out 55 pounds.
Essentially leveraged as a form of high-tech turbocharging, here a small electric motor gives a modest fuel-free power boost to a direct-fuel-injected 2.4-liter four-cylinder engine.
Even as Ferrari and McLaren forge new territory with high-performance hybrids, plenty of examples of old-school power also will be on display at the Geneva Motor Show.
