Rhino, Inc used to rely solely on it’s sleeker body styles for product differentiation, but one supposes it was only a matter of time before they started offering bigger models than their competition at Hippo Co. It is a brazen attempt by Rhino, Inc. to steal market share and muscle their way into more endangered species funds. The comparison with elephants is apples to oranges. The elephant is clearly a cargo animal and for that reason size does matter. The offerings from Hippo and Rhino are more sport/utility (although one concept show did feature a Rhino model slightly larger than the base elephant, mass production was never seriously considered).
The Ostrich did register a top speed of 55 MPH in the late 60’s/early 70’s, but fuel was cheap then. The fuel shortages of the mid/late 70’s rendered the Ostrich subject to the “guzzler tax”. Instead of changing the body design to conserve fuel, less power was used, hence the current top speed of 40 MPH. Pronghorn chose to go with more modern technology and added a turbocharger. Bone density was decreased slightly as well, to lower the overall weight. Rumor has it that Cheetah is deep into R&D to overcome Pronghorn’s advances. The research is top secret, but don’t be surprised if you see a Cheetah Sportster tooling around the Seringeti in the near future.
