The Characteristics of the BMW 5L V10 engine used on BMW M5 and M6 cars

2. Introduction
Whenever BMW M presents
a new M automobile, the
focus of attention is
traditionally on the power
unit beneath the bonnet.
This is particularly the case
with the new M5: across the
world, its V10 engine is
considered to be one of the
most fascinating drive
concepts featured in a
production car

3. This technological masterpiece does
not only sport the same number of
cylinders as its Formula 1 BMW
Williams F1 racing counterpart, but
also shares its high-revving concept

4. The V10 is the only high-revving power unit to be featured in a series-production
car. The M5's engine has ten cylinders, a cubic capacity of 5
litres and produces a maximum output of 507 bhp and a maximum torque
of 520 Newton metres

12. A V10 Engine?
A V10 engine is an internal combustion engine with 10
cylinders. The engine has five cylinders on each side called
banks. The two banks form a "V" shaped angle. All ten pistons
turn in a common crankshaft.
A V10 can be powered by different types of fuels, including
gasoline, diesel and natural gas.
It is more powerful and with more torque than a V8 engine, but
also lighter than a V12.
V10 engines are mostly used in exotic and sportive cars.

13. A V10 Engine?

14. Main Characteristics
The BMW 5-liter V10 is derived from BMW Formula 1 team, after
Formula 1 banned V10 engines and start using V8 engines in
2005.
It was used on BMW M5 and M6 cars
High Horse Power
High RPM
This engine, particularly, is build entirely from aluminum.
It is highly compact and extremely light.

15. Main Characteristics(cont.)
It uses DOHC, which means double overhead camshaft. It is
characterized by two camshafts located within the cylinder
head, one operating the intake valves and one operating the
exhaust valves.
It uses a multi point fuel injection system. This injection system
delivers the exact correct amount of fuel to each engine cylinder
at the correct time. A multi-point system uses one injector for
each cylinder, typically mounted right where the manifold meets
the cylinder head.
High compression ratio, 12:1
Average fuel consumption

16. Design and Materials
V-shape engines provide more
power output
It is a compact, light and
efficient V-shape engine with
10 cilinders
The angle of the V-shape is 90
degrees and this makes it
more compact.
Most parts of the engine are
made from alluminum, which
makes it lighter
Double Overhead Camshaft
allows a wider angle between
intake and exhaust valves.
This allows more air to flow
which mean more power
output. This design reduces
valvetrain inertia since the
rocker arms are eliminated.

17. Power and Torque
High power output (507 HP)
and good torque(520 Nm)
High-revving normally
aspirated engine with a red
line of 8250 rpm
100 HP per liter output, its
specific output being on par
with that of racing cars.
25 per cent increased
performance than its
predecessor engine.
High compression ratio, 12:1,
produces more power

18. Fuel Comsuption and
Emissions
The BMW 5.0L V10 has a combined fuel comsuption of
14.8 l/100 km
It is actually a low value compared to the high output of the
engine and to other engines with the same power output.
Besides the high performance, the engine is also both Euro
4 and US LEV2 emission levels compliant. Which means
the level of emissions are greatly reduced.

19. Summary
Everything about this engine the
power output, the layout, the
four-pump lubrication
arrangement, the 50 sensors
and the 8,250rpm –all are
hallmarks of a supreme design
effort
Thanks to this, BMW has got to
make a masterpiece: the 5 Litre
V10
