good looks and matching high performance short term acceleration,
superb braking and road-handling for local competitions and excitement
Format:: Steel safety frame sportscar with hard-top or ragtop
Capacity: Two adults plus two children (1 m) all seated & strapped-in, or two seated adults with luggage
Chassis: Extremely light tubular steel space-frame chassis with stressed aluminium body panels.
Front suspension: double wishbone, fully adjustable, inboard springs and dampers
Rear suspension: fully independent double wishbone, alternate: De Dion tube design.
Motors: 4 electric disk-format motors 'near each wheel' (With current & velocity monitors, also used for regenerative and reactive braking)
Batteries: standard lead-acid array in chassis floor-tray endurance c. day with vigourous use over 3 hours, light manoeuvre 6 hours
Recharge: Standard single phase 250v - 120v at 50hz - 60 hz a/c, self selecting and regulating for optimum charge in 8 hours,
with optional 'emergency 2-hour fast charge'
Steering: Ackermann steering geometry rod connected to disk-format incremental step motor
Control: Drive-by-wire 5cm central control column for left or right driver
- Lateral: Left Right direction log-law (large movement small control around centre) above 10 kph, rate integrator at low speed
- Aft and fore & emergency brake, operational brake gentle speed increase, deecrease & full-forward emergency stop
- feedback 'feel' (artificial resistance) against sudden accidental manipulation.
- Controls slowly return to neutral if hand removed momentarily, initiates straight stop if released more than 3 seconds
Anti-skid: Road surface traction calculated between front and rear wheel drive/velocity
Aerodynamics: Fineness (C/D) ratio 0.37 laminar flow
-To combat lift, several features include
- Front wings: fitted close to the tires to reduce turbulence.
-A small lip on wings angles air upward and creates a small amount of down force.
-A plastic duct behind the ventilator directs air straight out, creating down force and reducing turbulence.
-The air-vents on the nose-cone Vehicle specifications
