The
new BMW ActiveHybrid 7: Efficient Dynamics in luxurious style.
BMW Asia has announced the arrival
of the second generation BMW ActiveHybrid 7, a move that is in sync with the
ongoing development of BMW‟s intelligent hybrid drive systems.
The new model sets itself
apart with lower fuel consumption and emissions, as well as innovative
auxiliary functions. This latest evolution stage uses BMW TwinPower Turbo
technology with a six-cylinder in-line petrol engine displaying impressive
high-revving characteristics, torque and efficiency. The cutting-edge petrol
engine with BMW TwinPower Turbo technology is the 320 hp variant of the unit
fitted in the new BMW 740Li and replaces the eight-cylinder engine used up
previously.
Other hybrid components
include the 55 hp synchronous electric motor, the hybrid-spec eight-speed
automatic transmission, a lithium-ion high-performance battery and power
electronics underpinning intelligent energy management.
Mr Neil Fiorentinos, Managing Director of BMW Group Asia said: “Efficient Dynamics technology continues to drive our cars with enhanced power while not compromising on their fuel efficiency and CO2 emissions. The various Efficient Dynamics components found in this flagship BMW hybrid limousine have come together to form a powerful and harmonious whole that has struck an outstanding balance between performance and fuel economy.”
A full Hybrid Car:
Ability to achieve zero tailpipe emissions.
With system output of 354 hp
and peak torque of 450 Nm, the new BMW ActiveHybrid 7 accelerates from 0 to 100
km/h in just 5.7 seconds. At the same time, the limousine posts average fuel
economy of 6.8 litres per 100 km (which is 14 percent less than a conventional
BMW 740Li) and CO2 emissions of 158 g/km. The new BMW ActiveHybrid 7 can also
run purely on electric power with a maximum of 210 Nm of torque on tap. The new
BMW ActiveHybrid 7 is able to travel at a speed of 60km/h based purely on its
electric drive. However, If the hybrid battery has sufficient charge and is met
with optimum conditions like ambient temperature, clear traffic conditions and
light-footed acceleration, the car can easily cover a distance of up to four
kilometers (at a speed of 35km/h), almost silently and with zero tailpipe
emissions.
The new BMW ActiveHybrid 7
Series is further packed with state-of-the-art technologies, including; BMW
TwinPower Turbo technology featuring twin-scroll turbocharging, High Precision
Direct Petrol Injection, Double-Vanos variable camshaft timing and VALVETRONIC
fully variable valve timing. The reduced friction core engines, furthermore,
come with a lightweight all-aluminium crankcase, which is a boon for both the
efficiency and the agility of the ActiveHybrid 7.
The ActiveHybrid 7 is further
partnered by a highly sophisticated eight-speed automatic transmission, which
stands out for its excellent efficiency, compact construction and innovative
gearset design.
Auto Start-Stop, Brake Energy Regeneration, ECO PRO mode.
The BMW ActiveHybrid 7 comes
equipped with an Auto Start-Stop function, which can cut fuel consumption by up
to 6 percent. The standard specification also includes Brake Energy
Regeneration, meaning that power for the vehicle electrical system is only generated
during overrun and braking phases where possible. When the engine is under
load, the alternator can often be disengaged. This not only means that
electricity can largely be generated with zero impact on fuel consumption, it
also endows the luxury sedan with even livelier acceleration. Finally, the
Driving Experience Control switch gives drivers the option of selecting the
extended ECO PRO mode which, by modifying the powertrain management and
programming the heating and air conditioning, heated seats and exterior mirror
heating to operate for optimum efficiency, fosters economical driving which –
depending on the individual driving style – can reduce fuel consumption by as
much as 20 per cent.
New coasting mode and advance preparation of hybrid drive system.
The extended ECO PRO
functionality includes the new coasting mode, which is designed to decouple the
combustion engine when it is overrunning at speeds between 50 and 160 km/h. In
coasting mode, the BMW ActiveHybrid 7 is subject to a far lower rate of
deceleration as it freewheels along the road with no engine braking effect and
minimal fuel consumption. By doing so, the kinetic energy built up by the
vehicle can be harnessed and – through forward-thinking driving aided by the
proactive driving assistant – fuel savings of up to five per cent can be
achieved. The coasting function is clearly visualised for the driver‟s benefit in the multifunctional instrument cluster and the central
Control Display, and can also be deactivated if desired.
Intelligent lightweight design
brings further reduction in fuel consumption and CO2 emissions.
Intelligent lightweight design
is integrated into all areas of BMW vehicle development work and into all
components, from the body and engine to the suspension. Besides high and
ultra-high-tensile steels and plastics, state-of the-art composite materials
are also employed. Finally, increased use of aluminium components in the engine
and suspension systems as well as for the bodywork has also further reduced the
weight of the relevant assemblies.
Premiere: Electric Power Steering included as standard.
The new BMW ActiveHybrid 7
comes equipped with Electronic Power Steering (EPS), which uses an electric
motor to provide steering assistance. EPS only operates when steering
assistance is actually required: no electrical power is consumed during
straightline driving or steady-state cornering. Noticeable attributes of this
system include not only its high efficiency and low weight, but also high
steering precision with good feedback, and comfort-enhancing self-centering and
anti-roll characteristics. Drivers also have the benefit of the steering system‟s standard Servotronic function, which has a more direct setup overall
and requires less steering effort.
Aerodynamic streamlining.
Reducing aerodynamic drag also
helps to lower fuel consumption. As the excellent drag coefficient figure of cd
= 0.28 would suggest, the aerodynamics of the new BMW ActiveHybrid 7 has been
finely honed in a state-of-the-art wind tunnel. The optimised aerodynamics also
brings benefits for acoustic comfort and roadholding. In particular, the
vehicle‟s underside plays an instrumental role in minimising lift forces, as
the aerodynamically efficient design with streamlined panelling provides a high
degree of sealing. Also, the front aprons are designed to create an “air
curtain” effect which reduces turbulence around the front wheels – again
reducing drag. The aerodynamically designed wheel arches and various air
deflectors likewise have a fuel-saving effect.
Latest Connected Drive Features
Apart from the latest
Efficient Dynamics features, the new BMW ActiveHybrid 7 also comes equipped
with various BMW ConnectedDrive technology including, the Anti-dazzle High-Beam
Assistant; the Mobile Office and voice control; and a new-generation
Professional navigation system with 3-D display, just to name a few.
The new BMW ActiveHybrid 7
will be available at Performance Motors‟ showrooms
from 5 October 2012.
