File Type:
PDF (Portable Document Format)
Image Quality:
Top quality images/graphics and diagrams designed for clear display. Recommended to use Adobe PDF Reader for optimal viewing.
Binding:
Not applicable (Digital PDF download)
Paper Quality:
Not applicable (Digital PDF download); printable pages recommended for on-site use.
Powertrain Type:
Electric Motor
Motor Type:
Typically series-wound DC or AC induction motor, depending on specific GEM model variant.
Horsepower Rating:
Varies by model, typically in the range of 3-5 hp continuous for standard LSEV configurations, with peak output potentially higher.
Torque Rating:
Not typically rated in conventional automotive terms, but electric motors provide instant torque.
Energy Source:
Electric Power
Battery Type:
Typically deep-cycle lead-acid batteries (e.g., 6V or 8V) wired in series to achieve desired voltage (e.g., 36V, 48V, or 72V). Lithium-ion battery packs became more common in later years.
Length:
GEM vehicles typically range from 7.5 to 10.5 feet (approx. 2.3 to 3.2 meters), depending on the specific model (e.g., E-Series, E4).
Width:
GEM vehicles typically range from 4.5 to 5.5 feet (approx. 1.4 to 1.7 meters).
Height:
GEM vehicles typically range from 5.5 to 6.5 feet (approx. 1.7 to 2.0 meters), including roof.
Curb Weight:
Varies significantly based on battery configuration and model, typically between 800 lbs to 1400 lbs (approx. 360 kg to 635 kg).
Payload Capacity:
Typically rated for 2-4 occupants and a small amount of cargo, with payload capacity often in the range of 200-500 lbs (approx. 90-225 kg).
Crash Test Ratings:
As a Low-Speed Vehicle (LSV), GEM vehicles are not subject to the same rigorous crash testing standards as conventional automobiles (e.g., NHTSA or IIHS ratings). Designed for operation on low-speed roads.
Braking System:
Hydraulic disc brakes on all wheels are common for better stopping power and modulation compared to drum brakes, especially for electric vehicles.
Lighting:
Standard headlights, taillights, brake lights, and turn signals for street legality and safety.
Seat Belts:
Mandatory three-point seat belts for all occupants.
Body Construction:
Typically constructed with a lightweight frame and body panels, often polymer or composite materials. Designed for low-speed impact absorption.
Audio System:
Base models may not have a radio. Optional radio or basic entertainment systems might be present, often with limited functionality.
Advanced Features:
Very limited to non-existent. Primarily focuses on core vehicle operation. No advanced driver-assistance systems (ADAS) are typically found on GEM vehicles of this vintage.
Connectivity Options:
None. Designed as basic transportation, without Bluetooth, Wi-Fi, or cellular connectivity.
Dashboard Display:
Basic instrumentation including a speedometer, battery charge indicator (state of charge meter), and indicator lights for charging, lights, and turn signals.
Battery Maintenance:
Regular inspection of battery terminals for corrosion, checking electrolyte levels (for flooded lead-acid batteries), and ensuring proper charging cycles. Specific interval recommendations vary by battery type and usage.
Brake Inspection:
Recommended at least annually or every 10,000 miles (16,000 km), focusing on pad wear, rotor condition, and hydraulic fluid levels.
Tire Rotation:
Recommended every 5,000-7,500 miles (8,000-12,000 km) to ensure even wear.
Brake Fluid:
Typically DOT 3 or DOT 4 hydraulic brake fluid. Refer to manual for specific grade.
Coolant:
Not applicable for air-cooled electric motors. Some models might have coolant for battery thermal management if equipped with advanced battery systems, but less common for 2009.
Common Battery Degradation:
Degradation of lead-acid batteries over time, leading to reduced range and charging capacity, is a common characteristic of LSEVs of this era.
Controller Faults:
Occasional failure of the motor controller due to heat, vibration, or electrical surge can cause loss of power or erratic behavior.
Charging System Issues:
Problems with the onboard charger or charging port connection can prevent proper charging.
Manufacturer Origin:
GEM (Global Electric Motorcars) was founded in 1998 and has undergone several ownership changes, including being acquired by Chrysler in 2000, and later by Polaris Industries in 2011.
Development Focus:
GEM vehicles have consistently focused on providing eco-friendly, efficient, and low-cost transportation solutions for specific urban and campus environments.
Manufacturing Location:
Primarily manufactured in the United States (e.g., Detroit, Michigan and initially Buffalo, New York).
Industry Awards:
GEM vehicles, as niche products, are less likely to have received broad automotive industry awards in the same vein as conventional vehicles. Their recognition is more in the realm of sustainable transportation solutions.
Consumer Ratings:
Customer satisfaction varies, often depending on the user's specific needs and expectations for an LSEV. Durability and range are common points of discussion.
