Enough Room in the Boot for Beverage Cases
Mazda MX-5’s new interior has more practical
storage compartments as well. There are three storage compartments in
the rear wall of the cockpit alone, as well as bottle holders in each
door and cupholders in the centre console. And the new boot – as a
special request from European customers – can now hold beverage cases,
containing 12 1.5-litre bottles, carried upright.
Mazda has given the latest MX-5 two new engines
from the MZR petrol family, a 2.0-litre four-cylinder and – only for
Europe – a 1.8-litre unit. Both engines meet Euro Stage IV emission
standards and are mounted longitudinally under the bonnet. Both are
lightweight and compact, with chain-driven, double overhead camshafts,
four valves per cylinder, sequential inlet-valve timing (2.0-litre
engine) and variable intake-air systems (VIS). The cylinder block and
head, as well as the oil pan sump, are made of aluminium.
The MZR 2.0-litre engine produces a maximum of 118 kW/160 PS of power
at 6,700 rpm and generates maximum torque of 188 Nm at 5,000 rpm. Even
more important: between 2,500 and 6,700 rpm, a minimum of 90 percent of
engine torque is always available. The Mazda MX-5 with a 2.0-litre
engine has a top speed of 210 km/h (130 mph).
The MZR 1.8-litre engine produces a maximum of 93 kW/126 PS of power at
6,500 rpm and 167 Nm of torque at 4,500 rpm. This entry-level model has
a top speed of 196 km/h (122 mph).
Manual Five-Speed and Six-Speed Transmissions Just As Precise-Shifting As Ever
The manual transmission mated to the MZR 1.8-litre
engine is an enhanced version of the five-speed transmission of the
previous Mazda MX-5 model. For the MZR 2.0-litre engine there is a
newly developed six-speed manual transmission that features even
shorter shift travel with especially low-effort shifting.
As was the case with the outgoing model, the new Mazda MX-5 has a
powerplant frame made of pressed aluminium in the transmission tunnel.
This frame rigidly connects the transmission and the rear axle
differential, to brace the chassis and suppress chassis flex during
heavy acceleration. This feature, which functions like a strong
backbone, has also been applied in a similar way to the outgoing model
and to the Mazda RX-8, which is built on the same assembly lines with
the new Mazda MX-5 in Japan.
The briefing given by Programme Manager Takao
Kijima to his engineering staff for developing the body and chassis of
the new Mazda MX-5 was very clear. The newest version of the legendary
model line up should also be just as compact and lightweight as
possible. The basic, front midship engine layout is retained, along
with rear-wheel drive and an ideal weight distribution between the
axles.
Jinba Ittai – Oneness Between Horse and Rider
While some aspects of the third-generation Mazda MX-5 are even better
than its predecessor, it retains all the original virtues for which the
Mazda MX-5 is rightly famous. All MX-5 generations have reflected the
Japanese ideal of Jinba Ittai, the symbiosis between rider and horse.
The expression can be traced back to the Yabusame ritual, where an
archer shoots an arrow at a target while riding a horse. To hit the
bull’s eye, the rider and horse have to act as one – otherwise the
arrow will miss its mark.
Jinba Ittai served as guiding principle for
developing the driving behaviour of the new Mazda MX-5. Instead of
focusing on pure speed, developers worked to achieve the ideal of a
balanced driving machine that provides skilful drivers with high levels
of driving enjoyment without the need of a large displacement engine.
One way to deliver this ‘driving balance’ is
vehicle weight. Despite featuring more standard equipment and a stiffer
body shell, the new Mazda MX-5 is only about 10 kg heavier (depending
on version) than the outgoing model. Painstaking adherence to a “gram
strategy” paid off, especially in designing the body and chassis. By
weight, 58 percent of all body parts are made of highstrength or ultra
high-strength steel. The result is a Mazda MX-5 body-in-white that
weights 247.5 kg and is 1.6 kg lighter than the outgoing model.
Mazda also employed high quality steel with
strength of up to 1,500 Mpa for the longitudinal members of the body
frame and for reinforcement pipes integrated into the A-pillars. The
result is a monocoque body shell with 47 percent more torsional
(twisting) stiffness and 22 percent more flexural (bending) stiffness
than the body of the outgoing MX-5.
Many components are made of aluminium, including the bonnet, the boot
lid, upper and lower front suspension control arms, as well as the rear
wheel hub carriers, brake callipers and rear suspension spring seats.
In order to deliver the maximum in driving fun, the engine of the new
Mazda MX-5 has been moved 135 mm further to the rear of the 12 vehicle,
and the battery and fuel tank are now positioned closer to the car’s
centre of gravity. As a result, the third-generation Mazda MX-5 with
two passengers achieves an ideal 50:50
weight distribution over the front and rear axles.
Extensive Standard Equipment Package
The new Mazda MX-5’s standard equipment package includes two front
airbags, passenger seat airbag deactivation, 16-inch wheels with 205/50
tyres, height-adjustable steering wheel, an aero board wind-blocker,
heated glass rear window, retractable key, remote central locking and
an audio system. Side airbags, dynamic stability control and traction
control systems are either optional or standard, depending on
individual European markets.
Standard equipment for mid and high-grade models (depending on market)
includes 16-inch and 17-inch aluminium alloy wheels, a storage net in
the passenger foot well, steering wheel mounted audio controls, climate
control air conditioning, Xenon headlights, a leather steering wheel
and gear shift knob. Among the most important options are metallic
paint exterior colours, a black leather interior with seat heating, a
“LogIn” keyless entry and start system, Bose® audio system and an
anti-theft alarm system.
First-Time Employment of Side Airbags
The new Mazda MX-5’s passive safety system
includes an important innovation – side airbags for head and torso.
They are integrated into the seatback sides and consist of two
chambers, which are activated at the same time by a common gas
generator and a single inflator. The upper and larger chamber protects
the occupant’s head and remains firmer and inflated longer than the
lower chamber. In this way, safety engineers achieved an effect similar
to curtain airbags in a closed-body vehicle. The lower and somewhat
smaller airbag chamber is not as firm when filled and releases its air
quicker, which provides optimal protection for the torso. The aluminium
bonnet, like that of the Mazda RX-8, is designed to provide optimal
pedestrian protection. A shock cone structure on the inner bonnet panel
absorbs the majority of contact energy.
