Output of the recorded models ranges from 66 to 143 kW, with models rated in horsepower spanning 90 to 194 hp, using four- and six-cylinder engines with displacement from 4,525 to 6,788 cm³.

Recorded operating weight runs from 5,010 to 6,450 kg, wheelbase from 2,564 to 2,876 mm, and top speed of the listed models spans 40 to 40.1 km/h. The Ares family also included ATZ-badged versions with a narrower track width or adapted chassis for specialised applications.
Within the CLAAS line-up, the Ares sat between the smaller Celtis and the larger Axion series, aimed at arable farms with medium to higher power requirements. When buying a used Ares, the exact variant matters, as chassis, cab and hydraulic equipment differ between versions.
With rated outputs from 66 to 143 kW, the Ares fell within ISO 730 Category II to III for the rear three-point hitch, with a standard dual-speed power take-off at 540 and 1,000 revolutions per minute. The turbocharged John Deere diesel engines come from a manufacturer that remains active today and still supplies spare parts and service documentation for these model years.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
