Aptera (Classified As A Motorcycle - 230 Miles Per Gallon)
Aptera http://www.aptera.com/details.php
The first Operating Prototype achieved over 230 Miles per gallon!
Five years ago, Aptera's founder Steve Fambro endeavored to design and build a passenger vehicle that was safe, comfortable, and more fuel- efficient than anything ever produced. This aspiration, combined with his background in engineering, led him to an intensive study of aerodynamics, and composite aircraft construction. He hypothesized that a low-drag, aerodynamic body shape could be achieved without sacrificing comfort, drivability or safety.
What emerged, after much designing, conceptualizing, and constructing, was a prototype two-seat, three-wheeled vehicle. This first operating prototype achieved a stunning 230 miles per gallon, Building on this success, Steve expanded his Aptera team and created the Aptera Typ-1, which has been re-designed, re-engineered, and refined into a production ready vehicle. We are excited to announce that the Aptera Typ-1 is now available for reservations.
The Aptera was designed from the ground up as an electric vehicle, and later as an extended range electric vehicle. After building the proof- of-concept Mk-0, we hired the automotive design firm, 'eleven', to help us further develop the concept vehicle. The 'eleven' team, led by Jason Hill and Nathan Armstrong, made great strides in the development of the Aptera's body styling, interior design, and structural engineering.
Meanwhile, we refined the Aptera's shape to maximize efficiency using CFD (Computational Fluid Dynamics), developed and built advanced suspension and drivetrain components, and integrated a strong yet lightweight composite shell. Our entire process has been developed in- house exclusively by Aptera for the Aptera Typ-1. Our structural elements have undergone countless revisions of FEA (Finite Element Analysis) to be lightweight, robust, and manufacturable.
Electric & Gasoline Hybrid
The Typ-1 uses a commoditized, 'ruggedized' 3-phase motor controller designed for vehicular applications, and a 3-phase motor made for us by a company here in Southern California. The rear drive suspension, and the drive reduction, are all designed and made by Aptera. Since the Typ-1e (electric) and the Typ-1h (series plug in hybrid) have different battery needs, this may result in different battery manufacturers for the two models. The Typ-1e is designed to use a 10 KWh pack, while the Typ-1h uses a smaller pack. The cycles and DOD are different for both applications. We will announce further information regarding the battery lifespan and warranty policy well before we begin manufacturing the Typ-1 next October.
Diesel or Gasoline? Our first prototype, the Mk-0, was a parallel hybrid Diesel and achieved an average of 230 MPG at a steady state of 55 MPH. This was pure Diesel/mechanical drive with no electric assist. Diesel is attractive for its Carnot efficiency and the increased enthalpy of Diesel fuel vs gasoline. However, diesel contains lots of unburned hydrocarbons and NOX compounds, and it's impossible to get a small Diesel engine certified for emissions in California. Therefore, the typ-h uses a small, water-cooled EFI Gasoline engine with closed loop oxygen feedback and catalytic converter. This engine is coupled to a lightweight 12KW starter/generator. It's very clean and quiet.
