Munich. BMW is celebrating ‘50 years of Turbo Power in
motorsport’ in 2019. From a initial turbo engine behind in 1969 to the
latest P48 engine for a BMW M4 DTM, that already has 6 wins to
a name this season, there have been many stairs forward. Here’s an
overview of a expansion of a BMW Turbo engine in engine racing.
1969: BMW 2002 TI – Engine: BMW M121.
As a initial BMW Turbo racing engine, this four-cylinder, in-line
engine with a two-litre ability and turbocharger was a history-making
pioneer. Dieter Quester (AUT) won a European Touring Car
Championship in a BMW 2002 TI with turbo power. With 0.98 bar of
overpressure, a initial epoch of turbo engine generated approx.
280 hp during 6,500 rpm. The empty fan was theoretically able of
building a boost vigour of 1.76 bar, however, a vigour in the
cylinder would have been so great, that a cylinder conduct would have
carried purify off.
1976: BMW 3.0 CSL – Engine: BMW M49/4.
The BMW 3.0 CSL art automobile designed by Frank Stella (USA) raced during the
24 Hours of Le Mans (FRA) in 1976 with a BMW M49/4 turbo engine.
With a banishment of 3.2 litres, a boost vigour of 1.72 bar
authorised a engine to beget roughly 750 hp during 9,000 rpm. It took
a BMW Motorsport engineers a matter of weeks to arrange a exam car,
that done a competition entrance during Silverstone (GBR). However, as with the
art automobile during Le Mans later, technical issues prevented a good competition result.
1977: BMW 320 Group 5 – Engine: BMW M12/12.
From 1977, Schnitzer Motorsport ran a BMW M12/12 engine in a BMW
320 Group 5. Just one year later, Harald Ertl (AUT) won a German
Racing Championship with that really engine. The four-cylinder unit
generated usually brief of 400 hp, while a various grown serve by
Paul Rosche and his group in 1979 indeed exceeded a 500-hp mark.
1979: BMW M1 Group 5 – Engine: BMW M88/2.
In 1979, an considerable 1,000 hp of energy lay asleep in a BMW M88/2
engine for a BMW M1 Group 5. The mid-mounted engine could not really
unleash this energy until 1981, as a homologation of a automobile was
delayed. By that point, a BMW M1 Procar, that was homologated in
line with Group 4 regulations, had already achieved good celebrity with
a M88/1 naturally aspirated engine. However, a Group 5 version
brought with it advantages over a rivals from Porsche and Ford, who
were really clever during a time. These advantages eventually helped
Hans-Joachim Stuck (GER) to a prestigious feat during a Norisring in 1981.
1981-1987: Brabham BMW – Engine: BMW M12/13.
Based on a engine in a BMW 320 Group 5, Paul Rosche grown the
1.5-litre engine used in a Brabham BMW in Formula 1 in 1981. The
section essentially generated roughly 560 hp in races, though this performance
was augmenting all a time. In 1982, Nelson Piquet (BRA) claimed the
initial Formula 1 feat with BMW Turbo Power. One year later, he was
crowned universe champion in a Brabham BMW BT52. By this point, its
engine was generating 640 hp in competition mode, with 2.9 bar of boost
pressure. Its inheritor – a BMW M12/13/1 – was able of adult to
1,400 hp in subordinate mode, creation it a many absolute Formula 1
engine ever. As a patron engine, it was also used by other teams,
including ATS, Arrows and Benetton. Current ITR boss, Gerhard Berger,
took his lass Formula 1 feat with this engine in 1986.
2011-2012: MINI WRC and BMW 320TC WTCC – Engines: P14 and P13.
After a Formula 1 era, it took until 2011 for BMW Motorsport to run
another turbo engine: a P14, formed on a prolongation engine in the
Mini Cooper S, in a Mini Countryman World Rally Car, and P13 in the
BMW 320TC for a FIA World Touring Car Championship (FIA WTCC). The
energy was increasing dramatically, to 320 hp from a banishment of
usually 1.6 litres. The cylinder retard and cylinder conduct were largely
unmodified, display usually how strong a prolongation engine was.
2016: BMW M6 GT3 – Engine: BMW P63.
In 2016, a BMW M6 GT3 was a subsequent competition automobile to contest with turbo
power. The P63 engine was formed on a S63 prolongation chronicle and was
somewhat mutated to accommodate a final of motorsport. Thanks to M
TwinPower Turbo technology, a V8 engine with a banishment of 4.4
litres generated adult to 585 hp, depending on a classification. The
BMW M6 GT3 is still enjoying success with a P63 engine to this day.
Among other successes, this multiple has won a 24 Hours of
Spa-Francorchamps (BEL) twice and a FIA GT World Cup in Macau (CHN).
2018: BMW M8 GTE – Engine: BMW P63/1.
In credentials for entering a FIA World Endurance Championship and
a IMSA WeatherTech SportsCar Championship with a BMW M8 GTE, the
informed engine from a BMW M6 GT3 was reduced from a banishment of
4.4 to 4 litres to approve with GTE regulations. The P63/1 engine
consists of roughly 2,300 components – 985 of that are unique. 181
tools issue from prolongation projects, while over 700 were
grown from blemish generally for a P63/1 or eliminated to this
plan from other BMW Motorsport racing engines. Depending on the
classification, it generates between 500 and 600 hp and was, during the
time, a many fit engine that BMW Motorsport had ever
developed. Its biggest success to date came in a form of a GTLM
category win during a 24 Hours of Daytona (USA) in 2019.
2019: BMW M4 DTM – Engine: BMW P48.
On a 50th anniversary of a BMW Turbo engine, turbo
energy returned to a DTM in 2019. Like a 1969 engine, a BMW P48
is a two-litre, four-cylinder turbo engine, that is now able of
building some-more than 600 hp with boost pressures of adult to 2.5 bar. As
a regulations mention a limit volume of fuel, a detailed
growth work focussed essentially on efficiency. In this regard, it
not usually surpasses a P63/1, though also many complicated prolongation engines.
At 85 kilograms, it weighs usually half as most as a DTM predecessor.
The lightweight section boasts considerable total compared to a DTM
engines used previously: half a displacement, some-more power, less
consumption. The P48 engine won on a competition entrance during a 2019
season-opener during Hockenheim (GER).
