Bmw reveals new M4 DTM car
Bmw revealed the M4 DTM racecar for the 2014 campaign. Development work on the Bmw M4, which will compete in the forthcoming DTM season, has been in full swing in recent weeks and months. As of today, it is no longer possible to make modifications to fundamental areas of the car, heralding a new phase of preparations for the start of the season in Hockenheim, on 4th May. The forthcoming tests will primarily focus on optimising detailed aspects of the total package and understanding how to exhaust the full potential of the Bmw M4 DTM.
The new car will make public appearances out on the track at the official tests in Budapest scheduled from 31st March to 3rd April, and then at the final test in Hockenheim (14th-17th April). Like last year, the official presentation of all eight Bmw M4 DTMs will be held on 25th April in Munich.
Bmw Motorsport engineers started to look ahead to 2014 and began working on the development of the new Bmw M4 DTM well before the start of the 2013 DTM season. The first model made its first appearance in the wind tunnel at the Bmw Group’s Aero Lab on 22nd April 2013. Three hundred days after the first test in the wind tunnel, the Bmw M4 DTM took to the track for its track debut in Monteblanco, on 11th February 2014.
Among those to make valuable contributions towards achieving this goal were DTM drivers Bruno Spengler and Timo Glock, who took part in tuning tests at the Nürburgring-Nordschleife. I am proud to have played my part in the fine-tuning. – said Spengler – The chassis of the Bmw M4 Coupé is very sporty. The feedback from the front axle is extremely direct, and the grip on the rear axle is phenomenal. This car is the ideal basis for our car in the DTM.
