According to Autosport’s sister title Motorsport-Total.com, the curbs on the amount of private testing came into force on 1 March and will apply until the season finale at Hockenheim in October.
Teams will be allowed to carry out five days of testing for each driver either together or separately under new regulations approved by the German motorsport federation DMSB at the end of February.
This means teams will have the option of running both drivers together for five days or splitting the running across 10 days with one driver on each day.
BMW squad Schubert Motorsport, which will expand to three cars this year after signing Marco Wittmann to partner incumbents Rene Rast and Sheldon van der Linde, will theoretically be able to test the M4 GT3 for a maximum of 15 days but only with one driver at a time.
As per regulations: "A DTM driver may take part in a maximum of five limited DTM test days."
The ADAC has defined a ‘limited DTM test day’ as a driving activity by a DTM driver in a GT3 car carried out by a DTM team on the Pirelli tyres used in the championship.
Interestingly, there is no restriction on the number of tyres that teams will be allowed to burn through during a test day. Only a hard limit on the number of fresh sets of tyres has been stated in the regulations.
“DTM teams and DTM drivers should not use more than three new sets of tyres during a limited DTM test,” it reads.
