Video test: SerialDriver — Simagic Alpha EVO ULTRA: what is 28 Nm actually for?

Simagic Alpha EVO Ultra test context

SerialDriver evaluated the wheel base with a demanding circuit-and-car combination: Sebring and the Radical SR10, followed by a rally session with a separate SimPro Manager profile. That is a useful way to expose both sides of a high-torque Direct Drive wheel base. Sebring highlights kerb strikes, surface detail and high-load corners; rally driving tests countersteer speed, direction changes and oscillation control.

The Alpha EVO Ultra sits above the Alpha EVO Sport 9 Nm, Alpha EVO 12 Nm and Alpha EVO Pro 18 Nm. It replaces the former 23 Nm Alpha Ultimate at the top of the Simagic range.

What does 28 Nm really change?

Maximum torque is not the same as the force you should run continuously. The useful concept is torque headroom. When a simulator asks for a large steering-force peak, a wheel base with extra reserve can reproduce it without clipping as early.

That reserve matters during heavy compression, aggressive kerb strikes, fast weight transfer and cars with high steering loads. Instead of flattening several different forces into one maximum output, the base has more room to preserve their relative intensity.

None of this means that more torque automatically produces better lap times. A badly tuned 28 Nm wheel base can feel tiring, noisy or needlessly violent. The objective is to preserve information—not to turn every kerb into a fight.

Force feedback: fast, physical and demonstrative

The strongest impression from SerialDriver’s test is the familiar Simagic character: the Alpha EVO Ultra is lively and demonstrative. It delivers pronounced peaks and makes the steering feel physical, particularly with a nervous car such as the Radical SR10.

Detail and road texture

Small steering inputs and surface changes remain perceptible beneath the larger forces. On a circuit like Sebring, that separation is useful: road texture, kerb detail and chassis load should not collapse into the same sensation.

Torque build-up and clipping

The 28 Nm reserve gives the base room to build force progressively before a major peak. This is where the Ultra differs most clearly from a lower-torque model. The advantage is not constant heaviness; it is keeping strong effects distinct when the steering load rises.

Oscillation and filters

SerialDriver found the base reasonably controlled for oscillation, but also noted that it needs to be restrained through the software. SimPro Manager lets you work with damping, friction, game-requested effects and response settings. With 28 Nm available, tuning is part of the product—not an optional afterthought.

What to expect in iRacing, Le Mans Ultimate, ACC and rally games

The result depends on each game’s force feedback implementation, car and settings. The Alpha EVO Ultra’s reserve is most useful when a title sends dense information or large transient forces.

iRacing

On iRacing-style circuit sessions, high-speed load changes, kerb impacts and steering weight are the obvious areas to evaluate. A high-torque base can preserve stronger peaks without clipping, but the in-game strength still needs to be set car by car. The Radical SR10 at Sebring is a demanding benchmark because it combines a physical steering load with sharp chassis reactions.

Le Mans Ultimate (LMU)

SerialDriver specifically mentions LMU as a title that sends a lot of information. On Le Mans Ultimate, running every effect and filter too high risks masking tyre load and front-end behaviour. The Ultra has the speed and reserve to handle dense force feedback, but it benefits from cleaner, lower filter values rather than maximum intensity everywhere.

Assetto Corsa Competizione (ACC)

ACC’s GT3 and GT2 cars make sustained steering load, kerb detail and tyre behaviour more relevant than raw peak force. The 28 Nm headroom can keep those forces separated, yet an Alpha EVO Pro 18 Nm may already cover this use case for many drivers—especially over long endurance stints.

EA SPORTS WRC and Assetto Corsa Rally

Rally places more emphasis on rapid countersteer, surface transitions and the ability to let the wheel rotate freely through the hands. Separate rally settings with reduced friction or damping can make more sense than reusing a heavy circuit profile. The Ultra’s speed is valuable here, but excessive torque quickly becomes counterproductive.

SimPro Manager: one profile is not enough

A high-end Direct Drive wheel base should be tuned around the simulator and discipline. SimPro Manager gives access to maximum torque, damping, friction, game effects, steering lock and response behaviour. Firmware updates are handled through the same software environment.

For a practical starting workflow:

1. Set the correct steering range and verify the in-game calibration.
2. Reduce maximum torque before the first session.
3. Check clipping in the simulator with the chosen car.
4. Add only enough damping and friction to stabilise the steering.
5. Test over several consecutive laps, not one corner.
6. Create separate circuit, prototype/LMU and rally profiles.

Alpha EVO Sport, EVO, EVO Pro or EVO Ultra?

For many simracers, 12 or 18 Nm is the sweet spot. The Ultra becomes rational when the cockpit is already rigid, the steering wheels are already part of the Simagic ecosystem and additional torque headroom is a deliberate requirement.

Strengths and compromises

Verdict: who should buy the Alpha EVO Ultra?

The Simagic Alpha EVO Ultra makes the most sense for an experienced driver who already understands force feedback tuning and wants maximum reserve without leaving the Simagic ecosystem. It is particularly coherent with a rigid aluminium-profile cockpit and disciplines where strong transient forces, fast countersteer or heavy steering loads matter.

It is not automatically the best Simagic wheel base for every buyer. The Alpha EVO Pro 18 Nm remains the more balanced high-performance option for many GT, endurance and prototype setups. The Ultra is the step beyond: more headroom, more physical presence and more responsibility in the settings.

Frequently asked questions

Is 28 Nm useful in iRacing or ACC?

It is useful mainly as torque headroom. The objective is to preserve strong peaks and avoid clipping, not to run the steering at 28 Nm continuously. ACC and iRacing can both benefit from reserve, but an 18 Nm base is already sufficient for many drivers.

Is the Alpha EVO Ultra suitable for Le Mans Ultimate?

Yes, on PC. LMU can deliver dense force feedback, so careful in-game strength and filter settings are more important than maximum torque alone.

Can the Alpha EVO Ultra be used for rally?

Yes. Its response speed suits rapid countersteer, but a dedicated rally profile with appropriate friction, damping and torque is recommended.

Does it work on PlayStation or Xbox?

No. The Simagic Alpha EVO Ultra is listed as a PC-only Direct Drive wheel base.

Which cockpit is required?

A rigid cockpit is strongly recommended. For 28 Nm, an aluminium-profile chassis with a suitable wheel deck or front mounting solution is the coherent choice.

What is the best alternative within the Simagic range?

The Alpha EVO Pro 18 Nm is the closest balanced alternative. It offers substantial torque headroom while being easier to justify for a broad range of GT, Formula and endurance setups.
