YOKOHAMA develops "AERO-Y" EV Concept Car | Electric Vehicle News

Quote:
..............In designing the "AERO-Y" body, MOONCRAFT.CO., LTD. represented by Mr. Takuya Yura*, a racing car designer, cooperated with YOKOHAMA..................

Aerodynamic drag reduction on vehicles With YOKOHAMA’s proprietary tire aerodynamic technology, dimples are employed for the tire side that becomes outer surface when mounted on a car, and fin-shaped protuberances for the tire side that becomes inner surface. While the dimples help reduce aerodynamic drag on the tire, the fins generate air flow that pushes the car forward by increasing the air pressure in the front side of a wheel wells, thus making it possible to contribute to fuel efficiency improvement by reducing aerodynamic drag on vehicles.

It is a conceptual car manufactured based on the company’s desire to make users feel intuitive sense of "pleasure of driving". In developing the "AERO-Y", YOKOHAMA focused on "aerodynamic drag reduction" as the theme and intensively utilized its latest technologies cultivated at various divisions through the aerodynamics-based designing of tires and bodies and the development of aerospace products and HAMATITE adhesives and sealants.

Shell in carbon fiber. Attention technicians focused on improving aerodynamics and went so far as to draw properly sidewalls (called BluEarth-EV) to optimize the air resistance. The shell is carbon fiber, in order to limit the weight to 1,285 kg (including batteries) and the union of the various parts is obtained by gluing the Hamatite, an adhesive developed by Yokohama itself.

Central engine. Aero-Y will be used to participate in races electric vehicles in Japan and three-phase motor 215 kW and 370 Nm placed at the center of the car and pack 56 kWh lithium-ion batteries.

Quote:
Air flows turbulently inside the wheel wells when a vehicle is moving, and some of this air flows out alongside the vehicle and causes aerodynamic drag to worsen. YOKOHAMA has tackled this problem by pursuing research using both aerodynamic simulations and wind tunnel testing.
Quote:
This technology was unveiled today at the 26th Computational Fluid Dynamics Symposium being held at the National Olympics Memorial Youth Centre in Tokyo until December 20, and is also to be presented at the Tyre Technology Expo 2013 in Cologne, Germany, from February 5, 2013.
I can move this car and it's tires into a thread of it's own.

FYI: There is a document download in that last link (above).

I've had a tape measure on my rear wheel well. it's ~28" diameter. I believe the largest Moon™ disc made is 30".

It might work to get one [1ea] disc and then re-roll the circumferential edge to fit the wheel well, then cut it in half and pull the edge down to a 28" diameter and then bead and wire-roll the cut edges with a deeper crown.

Hey presto! Spun aluminum fender skirts.


New thread? Bridgestone vs Yokohama.

The car drawing deejaaa posted sure doesn't look like anything anyone at GM Design would come up with. It doesn't even match the description. My money says it's the lame creation of some magazine or newspaper's Art Dept.

I agree.

The closest thing it comes to is this.

This is the 1964 GM Runabout car from the New York World's Fair, a three-wheeled car complete with shopping cart! (photo and info at http://www.discovery.com/area/techno...964/trans.html)

Actually, it could be a hybrid of the lower one on this book cover and the Runabout.

1985 Porsche 911 Long-Term Road Test - Miscellaneous


http://drivingphilosopher.blogspot.c...1_archive.html

Quote:
30 years ago Porsche was planning to build a low emission sportscar. With a wind slippery body (cw 0.25) and a low not too wide body, combined with a 4 cylinder 2 liter engine it would have been fast enough with less than 10 seconds from 0-100 km/h (yes this was still fairly fast in 1980) and a 200+ km/h top speed. And thanks to the low weight of less than 800 kg Porsche calculated a (ECE standard) fuel consumption of less than 4.8 l/100 km. Even today, this would be quite impressive.
