|The Laminar 3 is the
third iteration of an electric concept car that features
adjustable aerodynamics to best suit the driving
conditions. Providing better down-force when cornering,
and better aerodynamic efficiency for freeway driving.
In this updated concept this version addresses
aerodynamic efficiency though rear aerodynamics.
Borrowing from current day Hypermiling vehicles, the Laminar 3 concept adopts the aerodynamic advantage of a tapering rear section (boat tail) to reduce aerodynamic drag during freeway driving (Low Drag Profile).
To address the practical side of city driving the rear section of this concept can fold up. Reducing the overall dimensions of the car for easier parking and maneuverability, while also providing access to the rear boot(trunk).
While cornering this folded up profile acts as a rear spoiler providing extra grip to the rear tires (High Down-force Profile) 3 concept will actively alter between the Low Drag and High Down-force profiles, providing the user with the optimum combination of safety and efficiency through every driving condition.

- Drive system is two in wheel electric motors.
- Lithium-ion cells powers all the electrics.
- Car is a three seater with the driver seated centrally up front and two passengers seated behind.
- Adjustable front wing sits on a curved bearing system, with the wing being adjusted by a series of motors for quick transitions between streamline and down force modes.
- Adjustable rear wing hinges on a hydralic system, quick transitions between streamline and down force modes.
- Profile of body entirely streamline to prevent wind resistance.
- LED headlights and tail lights.
- Open transparent canopy made of strong polycarbonate.
- Regenerative brakes regain lost energy.
- Hubcaps have two electroluminescent rings one larger one to serve as an indicator and a smaller one for night visibility.
- Touch sensitive panels stretching either side of the interior allow for controls such as GPS and air-con settings.
- HUD provides the driver with speedometer, display panels on dash provide rear tail camera view and vehicle status.
- Handle and thumb stick controls replace steering wheel.
||Target Audience Show / Hide
With its 3 1/2 seater occupancy this concept caters to the small car market, possibly small families.
With an increased range due to its reduced drag profile, this concept would better cater for the fringe of users who would opt for a petrol driven vehicle as current electric vehicles don't have the range for that markets requirements.
||Development Notes Show / Hide
- Function came first in this design. Main priority was to make sure people could comfortably sit in the intended aerodynamic profile.
- The practicality of the rear section being able to fold up/away to solve the impracticality of a fixed boat tail design was an important feature to this design, so a variety of folding methods were explored all with their own advantages/disadvantages. The simple 45 degree hinging of the rear section was in the end the most practical (least complicated) method, and also provided the additional function of down force when folded up. The only downside being that it looks like a ridiculously large spoiler, not my intention but the result of creating a functional rear end
- There were a few other functional aspects that were refined before I could start to adjust and compromise with the aesthetics of this design. At this point I ended up refining and adjusting the look of the car (which at the time wasn't visually appealing as it could be, but it was functional). There were a half dozen variations of styling before it got to this current version, all were a challenge making this concept appealing without drastically affecting the aerodynamics of the vehicle.
