German motorsport powerhouse HWA has admitted that it is evaluating an entry into the Formula 2 Championship in 2019.
HWA, which is best known for running the Mercedes DTM programme and supplying the same manufacturer's powerplants for Formula 3, would add the F2 team to its expected participation in the new FIA Formula 3 Championship.
HWA was one of the 10 teams accepted by FIA F3 promoter Bruno Michel on a list discovered by Autosport - the new series replaces Michel's GP3 Series under his F2 contest on the Formula 1 undercard at European grands prix.
With Mercedes quitting the DTM, HWA's F2/F3 teams would run alongside its new partnership with the R-Motorsport Aston Martin entry to the German touring car series, as well as its Mercedes-affiliated Formula E squad using Venturi technology.
When asked about F3, HWA CEO Ulrich Fritz told Autosport: "I can only tell you that we are interested in doing International F3, but we have not made a final decision yet.
"As far as I know there is nothing officially done - I cannot say any more than we are interested in doing it."
Pressed on F2, Fritz added: "Doing this is quite interesting to us, but they [the programmes] need to fit together."
Sources suggest the HWA junior single-seater teams could be an avenue to bring on the manufacturer's young drivers.
This could raise speculation that newly crowned Formula 3 European champion Mick Schumacher, who has a strong association with the manufacturer and used its powerplants for his F3 successes, could be a contender for an F2 seat.
But Autosport understands Schumacher currently favours remaining with Prema, with which he has driven for three years in Formula 4 and F3, for his graduation.
Rumours had suggested that HWA could take over the F2 and F3/GP3 programmes of Arden International, but these have been denied by team principal Garry Horner.
Horner told Autosport that the team had already decided not to continue in the third tier, but that it will continue in F2.
"We decided to pull out of GP3 to concentrate on our F2 entries and lower activities down the formulas [including Formula Renault Eurocup and British F4]," said Horner.
"We're expanding our sportscar programme and we're looking at another activity at the moment not in open-wheel racing, where we think the future lies.
"There's come a time with GP3/F3 - we've been in the championship a long time, we've won the championship twice [with Mitch Evans and Daniil Kvyat], we have other areas we want to concentrate on, and we'll have a sabbatical and see how these other things go.
"Carlin were out of it, came back. DAMS have been in and out, and so on.
"It's really where the best market is for you and you have to do the best job."
Horner added that the junior single-seater landscape is difficult in the current era.
"Formula 1 and its support categories are going through a lot of change at the minute and we are developing as a business," he said.
"Not all of these young drivers are going to get to Formula 1 anymore - there's a good future in sportscar racing, they can go into that and enjoy the racing.
"It fits best with our activities - Blancpain [where Arden collaborates with R-Motorsport] is a very well-run championship and very enjoyable and that's what it should be about."
