Vehicle Height – The MEV shall not exceed 80 inches in height. (Primary requirement) (5)

Rationale: Lowest parking garage is 84 inches tall.

Vehicle Length – The MEV shall not exceed 220 inches in length. (Primary requirement) (5)

Rationale: Average parking garage is 240 inches long.

Vehicle ride height– The MEV shall not have a ride height lower than 4.1 inches. (5)

Rationale: USA speed hump height is max 4 inches per US DOT Traffic Calming ePrimer.

The MEV needs to not require an additional grade of driver’s license to be driven by the user. (5)

Vehicle weight – The MEV shall not exceed a gross vehicle weight rating of 20,000 pounds. (5)

Rationale: USA class C driver’s license is limited to 20,000 lbs.

2.2 VEHICLE PERFORMANCE – MEV needs to offer class competitive performance figures to be a desirable product in the market. (3)

The MEV needs to be able to be competitive in vehicle acceleration and braking compared to its competition. (4)

Vehicle Braking (Ideal) – The MEV should not exceed braking distance of 133 feet at 60 mph. (5)

Rationale: Tesla model 3 has a braking distance of 133 feet @ 60mph.

Vehicle Acceleration – The MEV should have an acceleration time from 0-60 mph no slower than 5.5 seconds. (3)

Rationale: Cheapest Tesla model 3 has a time of 5.3 seconds. While MEV is not looking to out-perform the Tesla in acceleration, it should not be significantly slower.

Vehicle Range – The MEV shall have a base range of no less than 250 miles. (5)

Rationale: This range is required to be competitive within this market segment.

Vehicle Top Speed – The MEV should have a top speed of at least 110 mph. (1)

Rationale: Customer interaction shows that a top speed of over 100 mph is desirable to be appealing.

The MEV need to be easy to recharge. (5)

Charging input – MEV shall accept 110V-480V charging station. (5)

Rationale: 110V is home charging while 480V is a Tesla supercharging station.

Charge speed – MEV shall be able to reach 80% charge from 0% in 15 minutes. (3)

Rationale: Tesla model 3 can charge up 200 miles in 15 minutes.

The MEV need to give the customer a sense of advanced technology. (3)

Vehicle Autonomous Driving Abilities – The MEV should have the option to support level 2.5 autonomous driving. (3)

Rationale: Market research indicates that EV customers are technology conscience in their vehicles.

Traffic-Sign Recognition – The MEV should have the ability to read and display road signs and speed limits. (1)

Heads Up Display (HUD) – The MEV should have the ability to support a HUD to display speed, blind spot detection, and signal changes. (2)

2.3 SAFETY – MEV is safe for customers both in preventative measures and active protection systems. (5)

MEV needs to be safe for the users in case of a crash. (5)

Airbags – The MEV shall have at minimum of 8 airbags within the vehicle. (Driver, passenger, side airbag curtains for all 4 windows, and two knee airbags for front row.) (5)

Telematics – MEV should incorporate a system to connect the user to emergency services in the case of a crash that prevents the user from accessing their phone. (5)

Rationale: There have been crashes where the driver is stuck within a vehicle and is unable to reach their communication device.

Battery safety: MEV shall have battery protection to prevent puncture of the battery pack if debris strikes the pack. (5)

MEV needs to have crash prevention systems to warn user of unsafe conditions. (5)

Vehicle Blind Spot Monitoring – The MEV shall have the ability to monitor its blind spot in real time and alert the driver if there is an object located in the blind spot. (5)

Rationale: Market research indicates that EV customers are technology conscience in their vehicles. Blind spot detection is a common standard feature in this market price segment.

Vehicle Backup Camera/Sensors – The MEV shall have a backup camera that displays a live camera feed of behind the vehicle during reversal and warn the driver in case of object within sensor range. (5)
