If you read our previous update regarding the Aptera, you already know that the company is now taking deposits on their futuristic three-wheeled machine. I was able to get in contact with Steve Fambro, the man behind the Aptera, and I'll share some design and technical details in this post. With production of the Aptera expected to start in October, there are still some details that must remain confidential. But, the good news is that you are likely to get more information here than you've gotten anywhere else up to this point. Steve believes that aerodynamics will start to shape our vehicles in the future much more than they do now. Many who see the Aptera believe it looks much like an airplane, and this is no coincidence -- it's because the shape has been honed by the wind. So, in a way, Steve believes that the introduction of the Aptera marks a jump into the future of automotive design in more ways than just the alternative powertrain.

I have a brief update from Robert at Robert Q. Riley Enterprises about the status of the XR3 diesel\electric hybrid prototype. I can also share with you a few pictures of an XR3 body under construction. The process of creating a body from scratch requires building up a foam core that is larger than the desired end shape and then cutting and sanding it down to the correct size and shape. After this is complete, the fiberglass cloth is layered over the foam plug and the resin is applied over the cloth. Next, the foam core can be reduced to the proper size and another layer of fiberglass can be added on the inside, creating a foam\fiberglass sandwich. The end result is a rather strong outer shell which will never rust. Alternatively, molds can be taken off a completed body to allow other bodies to be created with the exact same specifications.

As you can see from the pictures below, the final shape is starting to show up on this work-in-progress. The right side is nearly molded to the desired shape, and the left is being built up. Robert shared with me that he is in talks with a fiberglass company to get molds created to duplicate the finished shape of this body. Under this foam composite sits the backbone frame, which I have seen, awaiting the VW transaxle and three-cylinder diesel engine at the front and electric motor at the rear. A custom windshield will be added at the front of the body shell after the fiberglass work is complete. Again, we hope to keep our readers updated as work on this prototype continues. If anybody has any specific questions, I can forward them to Robert if I don't already have the answer.

Robert Q. Riley, who you may already be familiar with due to his past projects like the Tri-Magnum, is working on a new diesel\electric hybrid three-wheeled vehicle. Like other three-wheelers, this one will be a motorcycle when it comes to regulations in the U.S. Also, like his past projects, the plans for the vehicle will be for sale for consumers to purchase in order to build the vehicle themselves. Using fiber-reinforced-plastic, or FRP, the body shell will be constructed over the chassis, using the chassis as a jig to ensure a proper fit. Many people with the DIY spirit have already done this when building his past project vehicles. Check this site out for examples. And, check this site for more on three-wheelers.

Riley claims that the vehicle will be able to travel 40 miles on electric power only, and the vehicle offers plug-in capability. Lithium-ion batteries provide the power. Alternatively, the driver can choose to activate the small diesel engine, which, along with the electric motor, should be able to provide between 125-225 miles per gallon, depending on how much use the diesel powerplant gets. Interested in more? Good, because we plan to run a feature article next week after a visit to his shop.

Looking more like a spaceship or an imaginary vehicle out of the Jetsons than anything else currently on the road, the Accelerated Composites Aptera uses a diesel\electric hybrid drivetrain which they claim is good for over 200 mpg at a constant 55 mph, using nickel-zinc batteries. The performance appears quite livable, with zero to sixty times coming in at 10 seconds. Using some sort of advanced carbon fiber technology for production hopes, the three-wheeled vehicle is expected to be available for less than $20 thousand.

It would be appropriate to mention that with three wheels, here in the U.S. at least it would be considered a motorcycle. This means that wearing a helmet and a motorcycle endorsement would be required in states where they are necessary for three-wheeled motorcycles. The normal motorcycle benefits would be included as well, such as being able to use carpool and high occupancy lanes and the like. As more information becomes available, we will keep you informed.
