The Japanese car maker is expanding the Mazda5 MPV range on the European market by adding a new fuel efficient 2011 model powered by a new 1.6-litre 4-cylinder diesel plant. 
The 2011 Mazda5 1.6 Diesel comes as a replacement for the previous 2.0-litre version, and besides weighting with 120 Ks less due to its aluminium alloy architecture, it also packs 5 additional HP, for a total of 115 HP (85 kW) and 270 Nm of torque.
Improvements have also been made in terms of consumption, as the 2011 Mazda5 1.6 Diesel requires 14.8 percent less fuel, which means 5.2-litres per 100 Km (45 mpg). CO2 emission levels have also dropped at 138 grams per Km *(13.2 percent improvement). 
Accelerating from 0 to 100 Km/h in the 2011 Mazda5 1.6 Diesel takes 13.7 seconds (top speed 180 Km/h) and as far as equipment, the new MPV comes fitted with manual air conditioning, height adjustable driver seat, electrical windows and side mirrors, and a 4-speaker sound system as standard.

2. Introduction

Small C-MAV, Big Value
Introduced during 2010, the New Mazda5 is already a big hit with
European customers, especially those with active lifestyles who drive a
high mileage.  Mazda now completes its new C-MAV line-up with the launch
of a 1.6-litre common-rail diesel version.  With this engine under the
bonnet, the New Mazda5 offers customers a powerful, small-displacement
turbo diesel that is frugal, affordable and fun to drive.  When
developing the new diesel version Mazda engineers set two key priorities
– class leading, low CO2 emission levels combined with low fuel consumption and a sporty and powerful driving feel.
“For the engine line-up of the New Mazda5, we placed emphasis on
environmental performance and fuel economy.  This aim led us to use
Mazda’s 2.0-litre direct-injection petrol engine with i-stop, and to
replace the previous 2.0-litre diesel engine with a newly developed
1.6-litre turbo diesel unit that leads the class in low CO2 emission levels.”
Hideki Matsuoka, Programme Manager Mazda5
Because the 1.6-litre diesel has a smaller-displacement, an
aluminium-alloy block and an 8-valve single camshaft (SOHC) layout, and
is mated to a compact and lightweight transmission, the New Mazda5 1.6
Diesel is up to 120 kg lighter than the model it replaces, which
contributes to lower fuel consumption.
It is also a highly efficient engine.  Engineers optimized the
mechanical parts of the 8-valve SOHC for low friction, and employed
highly-efficient Piezo injectors, all of which contribute to superior
combustion efficiency.  As a result, the New Mazda5 1.6-litre diesel
produces 5ps more power than the 2.0-litre diesel (standard power
version) it replaces, while using 14.8 percent less fuel and producing
13.2 percent less CO2.  It will appeal especially to
customers with active lifestyles looking for a flexible, do-it-all C-MAV
with affordable operating costs and superior emissions performance.

3. Powertrain

Lighter, more Fuel-Efficient and Quieter
Not only is the new diesel cleaner, it is also lighter than the engine
it replaces thanks to it’s compact size, aluminium block and SOHC
layout, with big benefits for fuel consumption.  Overall, the Mazda5 1.6
Diesel is 120 kg lighter, uses only 5.2 litres per 100km of fuel and
achieves Euro V compliance.  It does this in various ways, including
using a low compression ratio of only 16:1 — which lowers the combustion
temperature — and a highly-efficient exhaust gas recirculation (EGR)
cooler and EGR cooler bypass system.  This enables the engine to warm up
faster and reach peak combustion efficiency quicker from cold.
This 8-valve SOHC layout is also less complicated with fewer moving
parts than a DOHC system, which means that valve train friction is
reduced and NVH performance of the engine is optimised.  This included
enhancing the precision of the injection system by employing new Piezo
injectors that inject fuel at up to 1,600 bar.  These injectors allow
more precise injection control and multi-point injection to realise
smoother combustion.  These features – coupled to the New Mazda5’s
already extensive sound insulation measures – result in a smooth-running
diesel C-MAV that is comfortable to drive in every situation.
New Turbocharger, Higher Output
The variable-geometry turbocharger (VGT) helps the engine produce a
maximum torque of 270 Nm available across a wider rev range (between
1,750 and 2,500rpm) for improved day-to-day driving.  Together with a
maximum power output of 85 kW/115 PS at just 3,600rpm, the generous
torque supports a dynamic yet comfortable and easy-to-control
performance feel; and allows Mazda5 to reach top speed of 180km/h
(112mph) in sixth gear.
Clean-Running Maintenance-Free DPF
Mazda5’s new diesel also introduces a new maintenance-free diesel
particulate filter (DPF) system.  The new 1.6-litre diesel uses an
oxidation catalyst to increase the exhaust gas temperature and improve
particulate combustion.  This is user-friendly and also reduces costs
for the customer.

4. The New Mazda5

Unique Styling & Enhanced Interior Quality
The New Mazda5 introduced a completely new exterior look that employs
Nagare-flow design features, the new Mazda front face, a ‘hidden’
D-pillar and new horizontal rear lamps for a fresh appeal that is unique
to the C-MAV segment.  On the inside, Mazda5 has a new dashboard,
steering wheel and centre stack, along with new seats, materials,
colours and seat fabrics for enhanced quality feel.
Family-Friendly Practicality, Storage and Comfort
Immensely practical, the double sliding rear doors can be opened
automatically* or manually, and one of the largest rear door openings in
the segment, enable easier access and exit than rival vehicles.  The
Mazda5 has room for up to seven people and its seats can be easily
folded for a variety of seat configurations, including Mazda’s unique
Karakuri seat-folding functionality.  It has numerous storage
possibilities including an eight litre sub-trunk box*, six cupholders,
two bottle holders and an 11-litre glove box.  There are also two popup
tables with cupholders in the back of the front seats.
The cabin of the New Mazda5 is a comfortable place to be, offering
one of the most generous 2nd and 3rd row legrooms in the C-MAV segment.
 The front section of the driver/passenger centre arm rest is 15mm
wider, and the 2nd row seats can be adjusted to a maximum recline angle
of 50° and slide-adjusted over a range of 270mm.  The floor is raised
toward the back of the vehicle to give passengers in the back two rows a
clear view ahead and diagonally across the cabin.  
Ventilation outlets for the New Mazda5 are now placed higher than on
the previous generation, which improves comfort in the cabin on cold or
hot days and the rear passengers benefit from air ducts placed under the
front seats.  The cabin is also quieter and more comfortable at higher
speeds with wind noise cut by 10 percent, reduced suspension vibration
and engine intake noise, plus the fitting of new foam insulation.
* Depending on market and grade
Powertrain Line-up with new Mazda i-stop
Mazda’s new C-MAV has an engine line-up that focuses on Zoom-Zoom
driving fun coupled to low consumption and emissions.  Besides the new
MZ-CD 1.6 diesel, there are two petrol engines available, both with
smooth, precise-shifting six-speed manual transmissions.  Topping the
range is the MZR 2.0 DISI petrol engine with direct-injection and
i-stop, Mazda’s stop/start technology that offers great performance
coupled to double-digit reductions in fuel consumption and CO2
emissions.  It produces 110kW/150ps of power at 6,200rpm and 191Nm of
torque at 4,500rpm, to deliver a top speed of 194 km/h (121mph).
 Despite all this power, it uses 13 percent less fuel (6.9 litres per
100 km) and produces 15 percent less CO2 (159g/km) than the naturally-aspirated 2.0-litre petrol it replaced.
This engine is joined by an updated version of the popular MZR 1.8
petrol engine with a maximum output of 85 kW/115ps at 5,300 rpm and
maximum torque of 165Nm at 4,000rpm.  It is newly mated to the six-speed
manual transmission with a higher top gear ratio, which helps to lower
fuel consumption by 4 percent (to 7.2 litres per 100 km), CO2 emissions by 6 percent (to 168g/km) and to comply with Euro V.
When developing the new model, Mazda focused on achieving a “Harmonised
Dynamic Driving Feel” (named ‘Toitsu-Kan’) and the result is an
exceptional linearity in all responses – whether accelerating, turning
or stopping.  This provides both driver and passengers with a pleasant
and stable ride quality. 
Furthermore, the New Mazda5’s monocoque bodyshell is designed with
more high and ultra high-tensile steel reinforcements to be lighter,
stiffer and more crash-resistant than its predecessor.  Engineers added
new suspension, steering and aerodynamic components that deliver a more
linear steering feel for more control and predictability.  These chassis
updates are especially beneficial when combined with the updated 1.6
diesel version of the new Mazda5, which is 120 kg lighter than the
2.0-litre diesel it replaces, ensuring that this version has handling
attributes that make it both agile and easy to control.
Improved Body and Suspension Stiffness for More Control
Chassis engineers also improved local stiffness at bodyshell locations
which enhance vehicle control.  They enlarged the cross-section for the
D-pillars, the upper part of the liftgate, and the corner radius of the
liftgate opening, which stiffened the rear of the vehicle and lowers
liftgate opening displacement by 17percent compared to the previous
Mazda5.  Up front, additional spot welds were added to the apron section
of the front damper top mounts and at the base of the B-pillars, and a
closed-section structure was adopted for the rear pillars to increase
rigidity at belt-line level.
The suspension layout for the New Mazda5 employs MacPherson struts in
front and a multi-link suspension at the rear, twin-tube dampers in the
front and separate coil springs and monotube dampers with integrated
rebound springs at the back.  To deliver a linear driving feel,
engineers introduced new rubber couplings to the steering shaft joint
section and stabiliser (anti-roll bar) mounts, modified the dampers and
bushings for both the front and rear suspension, and increased all
spring rates.  These combined changes deliver a smoother response during
acceleration, deceleration and when cornering, and also improve
straight-line stability when driving at motorway speeds.
New Aerodynamic Design
The new front end design of the New Mazda5 not only sets it apart from
other C-MAV’s, it also contributes to an aerodynamic performance that is
unusually good for a C-MAV.  A new front lip spoiler, a flat engine
underfloor cover and front tyre deflectors work together to channel the
air under the vehicle efficiently, which reduces drag and helps to keep
fuel consumption down.  The design of the vehicle is also optimised to
improve the lift balance at the front and back.  These measures give the
New Mazda5 a drag coefficient of just Cd 0.30, one of the lowest in the
C-MAV segment.
Passive and Active Safety
The New Mazda5 includes a generous standard safety package, with six
airbags – front, side and curtain – and active safety features including
large 300mm ventilated disc brakes in the front and 302mm rear brakes,
four-channel ABS, electric brake-force distribution (EBD), brake assist,
traction control (TCS) and DSC; and an Emergency Stop Signal (ESS) that
warns the cars behind of a sudden braking manoeuvre by automatically
flashing the hazard lights rapidly.
With the 17-inch wheels, a tyre pressure monitoring system (TPMS) is
standard.  A further enhancement to the Mazda5’s safety is the
first-ever employment of Mazda’s Brake Override System, which always
prioritizes the brake pedal over the accelerator pedal should both be
engaged simultaneously, allowing the vehicle to be brought to a safe
Using Mazda5’s two electric sliding back doors* is now even safer
with the introduction of a new, highly sensitive touch-sensor strip,
running the length of the door’s leading edge, that automatically and
dependably returns the door to the open position if obstructed.  A
park-assist system is also available with four sensors in the rear
bumper that continuously measure the distance to any object when parking
in reverse gear.
* Depending on market and grade
The New Mazda5 is loaded with equipment that makes the trip fun and
easy.  It can be equipped, for instance, with an affordable, integrated
navigation system as an option that delivers 99 percent coverage of
Europe’s major markets.  It has 4 GB memory and 18 languages, a large
14.7 cm touch screen monitor, and a hands-free Bluetooth® telephone and
audio connection with external microphone.  This equipment package also
comes with an integrated CD player + radio that includes iPod®, iPhone®
(via optional connector cable) and MP3 CD capability, an AUX jack and
steering-wheel controls.
The standard equipment package features power-adjustable side
mirrors, manual air-conditioning, driver seat height adjustment, power
windows front and back with one-touch driver window operation, and power
door locks.  Also standard is a new four-speaker audio system with
digital signal processor (DSP) technology that reduces unwanted radio
noise, and a double tuner (exclusively for Europe) that ensures clear
radio reception.  It also has a FIX-EQ audio system that automatically
optimises sound characteristics according to the interior space.
Available equipment items include rear parking sensors, seat heating,
an in-dash 6 CD changer, Bluetooth® audio functionality for playing an
MP3 player, a Bluetooth® telephone system with voice recognition and
upgraded steering wheel control and Xenon headlamps – among many other
