From M121 to P48: An overview of a expansion of BMW Turbo engines in engine racing.

Posted on 15. Aug, 2019 by in BMW Canada

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).
