Below are some of the cars I have used to inform my speculations on the size, shape and characteristics (performance and 'smart' technologies) of the Apple Car. I have also included the scale calculations for the models I used in my earlier piece. Together, this data informs my reasoning in the articles posted here and here.
Toyota i-Road Concept Car
Toyota has not released full specifications on this vehicle, but they have allowed several test drives mainly for the automotive media since the 2013 Geneva Motor Show.

Comments: The Toyota i-Road is the closest concept I have seen to what I think the Apple Car, or some other motorcar 'disruptor' will look like. It is primarily designed for solo transport (but fits 2 at a pinch - an adult passenger can tuck behind the driver with knees akimbo).
To make this product more 'accessible' and 'desirable' I imagine Apple will seek to improve the following:
- Appearance of safety: Although the i-Road already has an airbag in its steering wheel, perception matters. Perception of safety could be influenced perhaps by adding smoother curves and reinforcing around the side to bring it in line with nearly the thickness of a conventional car door - say 10cm.
- Convenience: A hidden issue with motorcycles, bicycles, electric bicycles, scooters etc is that they all require some degree of 'preparation' by the riders as well as on-going maintenance. By 'preparation' I mean, for example, putting on protective equipment such as helmet, protective riding leathers, high visibility clothing, locking (e.g. to a nearby pole, as bicycle stands are relatively few and far between), charging, turning on/off safety equipment e.g. flashing lights, helmet storage, strapping of cargo/luggage. By maintenance, motorcycles and bicycles require considerable maintenance relative to a car. Taken together, these issues form a 'sub-conscious' impediment to many prospective users of those modes of transport. A future micro-vehicle should be able to easily overcome these issues.
- Comfort (seating & ride): For a vehicle of this type to appeal to people of all ages and physical abilities, the seat would need to be softer and more 'plush' than the cheap, thin vinyl seats provided on the i-Road, though not as substantial and soft as a car seat. Some suspension would also be expected.
- Comfort (noise levels): Some effort will go into sound suppression, although making it too quiet will make this vehicle dangerous to pedestrians. Electric motors of the size used here tend to have a high-pitched whine which will be difficult to suppress in any case, although road noise could be reduced by more sound and temperature insulation.
- Comfort (protection from elements): Expect this to be high on an Apple Car's list. A major inhibitor to people using motorcycles, scooters and bicycles more often is the level of physical comfort and protection from the elements. To serve as a commuter vehicle, it must enable people to arrive at work without being sweaty, drenched, hot, cold or exhausted.
- Comfort (entertainment system, 'smart' technology): This is a given in a proposed Apple Car, considering Apple's known foray with CarPlay and Apple Maps. Ease of integration with Apple products and sophistication of smart technologies would be one of the key differentiators of an Apple Car to future competitors, such as the i-Road.
- Performance: For the vehicle to succeed in the First World markets, it would need to be more versatile than purely a 'last mile' commuter (e.g. to the shops and transport hub). Rather, the vehicle should be able to be used on the highway 'at a pinch'. Consequently, increasing top speed to 80-110km/h would be likely. It is likely these performance improvements will be possible considering the 6-10 year span between the i-Road's debut at the 2013 Geneva Motor Show and the Apple Car's earliest launch date.
- Price: No price has been provided by Toyota, but a price under $10,000 has been suggested. This would bring it in line with the critical threshold I believe it would need to achieve to provide a sufficient 'value proposition' in the mind of the consumer.

Kyburz eRod
Specifications (translated from the Kyburz website using Google Translate)
Weight: 570 kg (incl. Bat.)
Battery: 18 kWh, 100 V / 180 Ah
Power: 40 kW / 140 Nm
Range: 100 - 130 km
Drive: brushless AC motor on the rear axle

Price: US$28,000 unassembled. US$38,000 assembled.
Comment: The eRod is almost twice the width and 25% longer than what I expect a future disruptive vehicle would look like. However, it does have the tubular frame I anticipate will be key and helps illustrate the sparseness of the underlying chassis that the 'future car' might have as its underpinning. Recall, Gordon Murray's 'iStream' car manufacturing methodology that seeks to scale the types of methods used in the manufacture of Formula 1 race cars. Note, the weight would need to be significantly reduced (to about 2/3rds or 400kg) - probably through super-strong composites. An enclosure for passengers is a given.

Calculations from Mini Cooper remote controlled car model
Actual Mini Cooper S dimensions: 3.7m long, 1.68m wide, 1.4m high.
Mini Cooper remote control car model dimensions: 200mm long.
Calculation of scale ratio:
(Actual length) 3700mm to (Model length) 200mm = 37:2 = 18.6:1 ratio.
Therefore width converts to: 90mm
Therefore height converts to: 76mm
Hence, the speculated dimensions of ‘future car’ converted to 18.6:1 ratio are:
Unscaled dimensions of the Apple Car:
Length: Approx 1.5 to 1.6m
Width: Approx 1m
Height: Approx 1.5 to 1.6m.
Scaled dimensions of the Apple Car:
Approximate Length: 81-86mm
Approximate Width: 54mm
Approximate Height: 81-86mm (can be lower, but it means for a very reclined seating position, possibly requiring seat adjustment technology)
Apple Car Model Dimensions used in photographs:
Length: 96mm (1.79m)
Width: 58mm (1.08m)
Height: 72mm (1.34m)
