Short answer: Choose Alpha EVO Sport 9 Nm if you want the most accessible Direct Drive base in the range and prefer moderate steering forces. Choose Alpha EVO 12 Nm if you are deciding between 9 and 12 Nm and want more torque in the same compact enclosure. Alpha EVO Pro 18 Nm is best suited to a rigid cockpit and a distinctly more powerful driving experience, while Alpha EVO Ultra 28 Nm is the flagship for very rigid rigs and drivers specifically seeking the highest torque in the range.
All four models use the modern Alpha EVO platform, but they do not suit the same driver or simulator. This guide compares 9, 12, 18 and 28 Nm by torque, size, steering wheel, mounting and driving discipline, helping you choose the right SIMAGIC wheelbase from the start.
SIMAGIC Alpha EVO 9, 12, 18 and 28 Nm compared
| Model | Max | Size and weight | Best suited to | Consider |
|---|---|---|---|---|
| EVO Sport | 9 Nm | 281 × 130 × 110 mm 6.236 kg | An accessible route into Alpha EVO, moderate FFB and lighter wheels | The lowest torque of the four models |
| EVO | 12 Nm | 281 × 130 × 110 mm 6.236 kg | Formula, GT, rally and more torque in the same compact format | A stable mounting solution is recommended |
| EVO Pro | 18 Nm | 317 × 130 × 110 mm 8.627 kg | Powerful sim racing, larger wheels and rigid cockpits | Places greater demands on the cockpit and wheel mount |
| EVO Ultra | 28 Nm | 359 × 130 × 110 mm 11 kg | Very rigid rigs, advanced training and the highest torque | Requires careful mounting, configuration and safety |
Alpha EVO Sport
9 Nm · 281 × 130 × 110 mm · 6.236 kg
The most accessible model for moderate FFB, lighter wheels and smaller rigs.
Alpha EVO
12 Nm · 281 × 130 × 110 mm · 6.236 kg
More torque than Sport in exactly the same compact size and weight.
Alpha EVO Pro
18 Nm · 317 × 130 × 110 mm · 8.627 kg
For a rigid cockpit, larger wheels and a distinctly more powerful experience.
Alpha EVO Ultra
28 Nm · 359 × 130 × 110 mm · 11 kg
The flagship for very rigid simulators and the highest available torque.
SIMAGIC initially launched EVO Sport, EVO and EVO Pro as one range. EVO Ultra 28 Nm arrived later, which is why it is missing from some older official comparison graphics. It is nevertheless a full member of today's Alpha EVO family and belongs in any current comparison.
SIMAGIC Alpha EVO 9 Nm vs 12 Nm: which should you choose?
This is the most important comparison for many buyers. Alpha EVO Sport 9 Nm and Alpha EVO 12 Nm have the same external dimensions, the same weight and share the range's core technology. The clear difference is torque: the 12 Nm model has 33 percent higher stated maximum torque.
Choose 9 Nm if price matters, you prefer moderate force feedback and want to move to a modern Direct Drive base without building an especially heavy-duty simulator.
Choose 12 Nm if you are undecided between the two, use larger or heavier steering wheels or want more torque without a larger wheelbase. Because the enclosure is identical, 12 Nm is the clearest step up without increasing the installation size.
Both models can be relevant for Formula wheels and lighter GT wheels. With larger round wheels and heavier GT wheels, the difference between 9 and 12 Nm becomes more noticeable because wheel diameter and weight affect how torque feels in your hands. You can also compare our sim racing wheels for Formula, GT and rally.
What do all Alpha EVO wheelbases share?
The range uses SIMAGIC's low-inertia motor platform, a 21-bit position encoder, a 180 MHz processor frequency and a stated 20 kHz response rate. The aim is for the motor to follow small changes in the game's force-feedback signal quickly and smoothly around centre.
SIMAGIC particularly highlights its Zero-Cogging control. Cogging is the stepped magnetic sensation that can occur when a motor turns slowly. Smoother motor control matters during small corrections, low loads and centre crossings. This should not be confused with higher torque automatically producing more detail; motor control, filters, wheel mass and the game's signal all work together.
Personalized Halo: more than decorative RGB
The illuminated ring around the motor shaft can be customised in SimPro Manager. It works as atmospheric lighting, but also supports telemetry-driven feedback. Depending on game support and configuration, the Halo can become a visual status indicator that changes with your profile or driving data.
Active cooling and connections
The range uses active cooling to manage temperature during long sessions. EVO 12 Nm, Pro and Ultra provide a broad selection of connections for SIMAGIC accessories and USB devices. Exact port use depends on model and accessory, so always check the product page and manual for your intended combination.
Ready-made profiles simplify setup
You do not have to start with a blank settings page. SimPro Manager includes game management and useful starting profiles, while One Click Profile Sharing lets you import a profile through a share code or file. This lowers the barrier for new users and makes it easy to test a proven baseline for titles such as iRacing, Assetto Corsa Competizione or formula cars.
A more open ecosystem: what does that mean?
Alpha EVO is designed with improved compatibility for third-party equipment. On PC, a wheel or accessory from another brand can often be used with the correct mechanical quick release, adapter and separate USB connection.
“Open Ecosystem” does not mean every third-party wheel communicates wirelessly through the base. Mechanical fit, buttons, paddles, displays and telemetry lighting are separate compatibility questions. Check the complete chain before purchasing. SIMAGIC wheels offer the most integrated connection, while third-party products commonly need USB directly to the PC.
Alpha EVO Sport 9 Nm: compact and accessible
Alpha EVO Sport 9 Nm has the same compact external dimensions and weight as the 12 Nm model. It is an attractive step into Direct Drive for a smaller cockpit or for drivers who intentionally prefer moderate steering forces.

Nine newton-metres provides clear steering load and a major step up from belt- or gear-driven systems. Its limit is most noticeable with a large, heavy wheel or when normal cornering forces are set so high that short peaks have less room.
Alpha EVO 12 Nm: the all-round choice
Alpha EVO 12 Nm retains the Sport model's compact size but adds one third more peak torque. This creates extra room for kerbs, compressions and fast force peaks without increasing the enclosure's size or weight.

You can still turn the strength down. The benefit of 12 Nm is not that the wheel must always feel heavier, but that more of the game's dynamic range can fit before the output reaches the base's ceiling.
Alpha EVO Pro 18 Nm: more torque for a rigid cockpit
Alpha EVO Pro 18 Nm is longer and heavier than the 9 and 12 Nm versions. Its larger motor provides more torque for heavy GT wheels, larger round wheels and drivers who prefer higher steering forces.

Pro is a strong enthusiast option for drivers wanting a large reserve without needing Ultra's 28 Nm. The additional output places greater demands on the wheel mount and seating position; flex in the rig absorbs part of the feedback.
Alpha EVO Ultra 28 Nm: the highest torque in the range
Alpha EVO Ultra 28 Nm is the largest and strongest model in the series. It weighs 11 kg, has a stated maximum power of 550 W and includes a kill switch for rapid shutdown.

Ultra is not automatically better for every driver. At the same usable steering force, the smaller models can also deliver highly detailed feedback. Ultra is primarily justified by its dynamic range, very heavy wheels, professionally oriented training or a specific need to reproduce high steering forces. Always begin at a low level and increase it gradually.
Mounting: bottom, side, front or desk
Alpha EVO Sport, EVO and EVO Pro support several mounting methods: bottom, side, front and desk mounting. Side, front and desk brackets are optional accessories. Front mounting can block the base's magnetic contact points, so select another method if you plan to use magnetic EVO accessories there.
Ultra is longer and heavier and should be installed with brackets explicitly approved for Ultra and 28 Nm. Do not assume that a bracket suitable for the 9–18 Nm models is automatically rated for the flagship.
How I would choose between 9, 12, 18 and 28 Nm
- Between 9 and 12 Nm: choose 12 Nm if your budget allows. You get more torque in exactly the same size and weight.
- Between 12 and 18 Nm: choose 18 Nm if you already have a rigid cockpit and genuinely want a more powerful experience. Otherwise, 12 Nm is easier to build around.
- Between 18 and 28 Nm: choose Ultra 28 Nm when maximum torque is a deliberate goal and the rest of the rig is designed for it.
- For a smaller or simpler rig: Sport 9 Nm is the natural option in the range.
- For larger or heavier wheels: begin your comparison at 12 Nm and above.
The best choice is not determined by the number on the box alone. Wheel diameter and weight, cockpit rigidity and the force-feedback strength you actually want to use all matter just as much.

Frequently asked questions about SIMAGIC Alpha EVO
Is SIMAGIC Alpha EVO 12 Nm worth it over 9 Nm?
The 12 Nm model has 33 percent higher stated maximum torque while retaining the same size and weight as the 9 Nm model. It is therefore the clearest choice if you want more torque or plan to use larger wheels without installing a bigger wheelbase.
Is 9 Nm enough for sim racing?
9 Nm can deliver a clear Direct Drive experience and suits drivers who prefer moderate steering forces. If you already know that you want stronger feedback, heavier wheels or a wider adjustment range, 12 or 18 Nm are more natural options.
Is 18 Nm too much?
Not when the output is configured correctly and the base is installed in a rigid cockpit. You do not have to use full strength at all times, but the installation must be designed for the wheelbase's weight and maximum torque.
Do I need 28 Nm?
Most drivers do not need 28 Nm for ordinary sim racing. Alpha EVO Ultra is aimed at users who specifically want the highest torque in the range, use a very rigid simulator or are building for advanced and professionally focused driving.
Which Alpha EVO is best for GT, Formula and rally?
Formula works well with 9 or 12 Nm because the wheels are generally smaller and lighter. For GT and larger wheels, 12 or 18 Nm are natural comparisons. For rally, the choice depends heavily on wheel diameter, how quickly it needs to rotate and the feedback strength you want to use.
Is SIMAGIC Alpha EVO difficult to configure?
You can start with ready-made profiles in SimPro Manager and import shared settings by code or file. Then adjust strength, steering angle and filters for your model and driving style.
Can I use a third-party steering wheel?
Often on PC, provided that the mechanical quick release fits and the wheel electronics are connected correctly, usually through a separate USB connection. Verify the exact wheel, adapter and button functionality before ordering.
Can I use a desk clamp?
A separate desk mount is available for parts of the EVO range, but desk strength and the selected FFB level impose practical limits. A fixed cockpit is the sensible solution for Pro and especially Ultra.
Conclusion
Alpha EVO Sport 9 Nm is the most accessible route into the range. EVO 12 Nm adds more torque in the same compact enclosure, Pro 18 Nm is intended for rigid cockpits and drivers seeking a more powerful experience, and Ultra 28 Nm is the flagship for very rigid simulators and maximum torque.
If you are mainly choosing between 9 and 12 Nm, the recommendation is simple: choose 12 Nm if your budget allows and you want more torque without a larger wheelbase. Move to 18 or 28 Nm when your cockpit, steering wheel and preferred driving feel justify the higher level.
