The Specs
At the heart of the Rotax E20 lies a powerful electric motor, delivering an impressive 20 kW peak output. This power translates to thrilling acceleration and top speeds exceeding 130 km/h (80 mph), did you get it? 130km/h (!) for an e-kart.
- Torque: Electric motors are known for their instant torque, and the E20 is no exception, offering exhilarating acceleration off the line.
- Weight: The kart weighs approximately 140 kg, including the battery, striking a balance between agility and stability.
- Energy Recuperation: A standout feature is its energy recuperation system, which harvests energy during braking to extend battery life.
- Battery: Equipped with a 2.5 kWh lithium-ion battery, the E20 provides sufficient range for competitive races and extended practice sessions.
The combination of these features ensures the E20 is not just eco-friendly but also a performance beast on the track.
If you want to see it head to head against the gas-powered alternative, here it is in a table vs Rotax 125 Max Evo:
Feature | Rotax E20 (Electric) | Rotax 125 MAX EVO (Gas) |
---|---|---|
Engine Type | Electric motor (20 kW peak output) | 2-stroke, single-cylinder, 125cc |
Top Speed | 130 km/h (80 mph) | 115-120 km/h (71-75 mph) |
Torque | Instant torque, high acceleration | Build-up torque, requires high RPM for max performance |
Weight | ~140 kg (including battery) | ~115 kg (lighter, including fuel) |
Energy Source | Lithium-ion battery (2.5 kWh) | Gasoline, 95 octane |
Refueling Time | 1-2 hours for a full charge (standard charger) | 2-3 minutes to refill the tank |
Eco-Friendliness | Zero emissions, low noise | Produces emissions, moderate noise level |
Maintenance | Minimal (no oil changes or exhaust servicing) | Regular maintenance (oil changes, carburetor tuning, etc.) |
Innovative Features | Boost Function, E-Braking, Energy Recuperation, Reverse Mode | None |
Cost of Ownership | Higher initial cost but lower ongoing expenses | Lower initial cost but higher fuel and maintenance costs |
Race Suitability | Excellent for modern eco-focused leagues and fair competitions | Widely accepted in most traditional karting competitions |
Whats new in Rotax E20 platform?
The Rotax E20 isn’t just about raw specs, it’s packed with innovative features that elevate the driving experience:
- Boost Function: This allows drivers to access an additional surge of power for overtakes or critical moments during a race.
- E-Braking: Electric braking systems ensure smooth deceleration while feeding energy back into the battery.
- Energy Recuperation: As mentioned, this system enhances efficiency, making the E20 one of the most sustainable options on the market.
- Reverse Mode: A handy addition, particularly in training scenarios or during casual driving, allowing easy maneuverability.
We discussed a lot about go-kart braking, but e-braking defiantly brings another aspect to the equation.
And There Are Environmental Benefits Also
In an era where sustainability is a priority as we can see in Formula E, the E20 aligns perfectly with the push for eco-friendly motorsports.
Its zero-emission operation reduces the carbon footprint of karting without sacrificing performance.
Additionally, there are benefits like quiet operation electric motors significantly reduce noise pollution, making karting more accessible in urban areas and indoor with strict noise regulations and of course, reduced maintenance if we take out of the equation the combustion engines. e-karts requires less frequent servicing, reducing waste and operational costs.
Comparison with Gas Karts
The debate between electric and gas karts is ongoing, but the Rotax E20 bridges the gap impressively.
It offer instant torque for thrilling acceleration, minimal noise, zero emissions, simplified maintenance, and consistent performance.
I personaly felt the gap in fuel based engines when I compete in rental karts that feels like a lottery, sometime you are on a fast kart, then on a slow one.
The cons are clear, higher initial cost compared to gas karts, limited range, and longer recharge times compared to refueling gas karts that takes only few minutes.
But despite these trade-offs, e-karts is gaining popularity for its reliability and eco-conscious design.
How it feels to drive on a e-kart?
From what I heard, the feedback from drivers has been overwhelmingly positive. Many highlight the instant acceleration as a standout feature, giving an adrenaline rush from the moment the lights go green. The kart’s predictable handling and smooth braking system have also earned praise, especially from racers transitioning from gas karts.
The Future of E-Karting
The Rotax E20 isn’t just a kart, it’s a glimpse into the future of motorsport. With increasing emphasis on sustainability, electric karting is poised to dominate, and the E20 is leading the charge. Its role in bridging the gap between professional racing and recreational karting ensures it will remain relevant as the industry evolves.
As electric technology advances, we can expect lighter batteries, longer ranges, and even more powerful motors, further cementing the E20’s legacy as a pioneer in electric karting.
What is the top speed of the Rotax E20?
The E20 can reach speeds of over 130 km/h (80 mph).
How long does the battery last in a Rotax E20?
The lithium-ion battery offers sufficient range for competitive races and practice sessions, typically lasting up to 30 minutes on a full charge, depending on the driving style.
Can the E20 compete with gas karts in performance?
Absolutely! The instant torque and advanced features of the E20 make it a competitive alternative to gas-powered karts.
Is the Rotax E20 suitable for beginners?
Yes, its intuitive controls and smooth handling make it an excellent choice for newcomers, especially in “Arrive & Drive” formats.
