Automobile Beaver - Beaver Automobile


Our Mission is to build the prototype of a road-ready automobile including a radial engine and a Continuously Variable Power Split Transmission (CVPST) to prove the performances and safety features of the new automobile having an all-aluminium unibody chassis. The Beaver is ready for the future application of pure electric drives (BEV), when battery technology has attained an acceptable level of performance and endurance.
The Radial engine, CVPST and chassis may be licensed independently. For instance the radial engine is lightweight and may be used in aeronautic applications. It can also be scaled up to drive trucks, buses, boats and other vehicles benefiting from the perfect balance of the engine. The CVPST may be inserted in existing automobiles providing the advantages of a power-split CVT.

CKE Technologies' mission is to build a four passenger road-ready automobile that averages better than 100 mpg. The "Beaver" automobile prototype includes a radial engine and a Continuously Variable Power Split Transmission (CVPST) in an all-aluminum unibody chassis that will be used to prove the performance and safety features of this new concept. The Beaver is designed to be BEV-ready (pure electric drive), once battery technology has attained an acceptable level of performance and endurance. According to CKE, the gain in performance is due to a holistic approach to automobile efficiency. The team states the curb weight of their vehicle is only 450 kg and super-aerodynamic body has a Cd=0.17 or less. CKE Technologies intends to use The Beaver automobile concept as a means to prove that by managing the weight, aerodynamics and using a light and efficient powertrain, an inexpensive 100+ mpg car is possible immediately, without waiting for any further technological breakthroughs.


Depuis les dix-sept dernières années, CKE a développé un nouveau concept de moteur en étoile avec un nouveau mécanisme interne. Une transmission continûment variable à puissance partagée (CVPST) a également été développée, et plus récemment, une carosserie monocoque tout en aluminimum à quatre passagers, ayant un coefficient de traînée très bas (Cx=0.16-0.17). Monsieur Mark Kmicikiewicz et Monsieur Ben Cowan, maintenant décédé, ont développé le projet à son état actuel. CKE a fabriqué un prototype du moteur qui peut fonctionner à des fins de démonstration de même qu’un modèle fonctionnel réduit de la transmission CVPST. Les dessins d’ingénierie des diverses composantes incluant le châssis et la carrosserie sont également disponibles en plus de la plupart des calculs par ordinateur. C’est Monsieur Ben Cowan, maintenant décédé, qui a financé le projet à ses débuts.
