The best way to listen to your favourite music in the Mazda CX-5 is on a BOSE® surround-sound system - with a new-generation energy-efficient amplifier and subwoofer.
Dynamic Performance
Regarding dynamic performance, the ultimate goal of the Mazda CX-5 development team was to make the vehicle move precisely according to the driver's wishes. To attain precise response, engineers concentrated on transferring the high performance levels of SKYACTIV TECHNOLOGY to the driver and used what is called a PDCA cycle to comprehensively analyze the driving process:
•Plan: the driver forms a vision of what he wants to do
•Do: the driver communicates his intention to the vehicle
•Check: the driver receives feedback from the vehicle confirming that its motion perfectly matches his intention
•Action: the driver proceeds to the next action
The superb ride quality of the Mazda CX-5, and its precise response, can be felt the instant the steering wheel and pedals are operated, and this feeling intensifies the more one drives it.
All-new Mazda SKYACTIV Chassis & Body
The Mazda CX-5 has newly-developed strut suspension in the front and a multi-link layout in the rear. The geometry of the suspension links and the bush characteristics are optimized to ensure light, linear steering response at mid-to-low speeds and excellent high-speed stability. The rear dampers also have a forward-tilting layout, increasing comfort even on rough road surfaces.
A newly-developed electric power assist steering system offers highly precise control according to vehicle speed. At mid-to-low speeds, it provides natural feedback and linear feeling from small to large angle inputs. At high speeds, it gives firm, confidence-inspiring feedback.
The brakes deliver easily-controllable, precise and assured braking performance from low to high speeds.
The lightweight yet rigid SKYACTIV-BODY framework is optimized for handling stability, low NVH and excellent collision safety performance. It supports the Mazda CX-5's rewarding and high-quality, responsive ride.
Care was taken with NVH to ensure the driver hears necessary audio feedback while actively eliminating intrusive noises. Noises were initially separated into road noise and engine noise. For each, the unpleasant low-frequency, mid-frequency and high-frequency noises were individually identified and efficiently eradicated, resulting in a quiet cabin environment.
To achieve smooth airflow under the vehicle and suppress eddies forming behind it, the air is directed upwards using a new underfloor design. The development team effectively reduced underfloor air resistance and optimized the aerodynamic shape of the upper body argeting an outstanding Cd of 0.33.
All-new Mazda SKYACTIV Powertrains
The SKYACTIV-G 2.0 petrol engine models have the world highest compression ratio of 14.0:1, and their 4-2-1 exhaust system prevents knocking and provides abundant torque from low engine speeds, enabling acceleration that precisely matches the driver's intention. Models with this engine achieve outstanding fuel economy, precise response, and a high-quality, linear and rewarding ride:
•FWD: Maximum torque of 210 NM at 4,000 rpm and maximum power of 121 kW/ 165 PS at 6,000 rpm
•AWD: Maximum torque of 208 NM at 4,000 rpm and maximum power of 118 kW/ 160 PS at 6,000 rpm
The SKYACTIV-D 2.2 diesel engine models have the world's lowest compression ratio for a diesel engine of 14.0:1, and a highly efficient two-stage turbocharger that delivers spirited and linear acceleration and exhilarating driving dynamics that surpass conventional diesel-engine vehicles. They also achieve outstanding fuel economy for a compact SUV with extremely clean emissions that clear Euro6 without the need of any NOx after-treatment systems. Two variants of the engine are available:
•A High Power version developing maximum torque of 420 Nm at 2,000 rpm and maximum power of 129 kW / 175 PS at 4,500 rpm.
•A Standard Power version produces maximum torque of 380 Nm at 1,800-2,600 rpm and maximum power of 110 kW / 150 PS at 4,500 rpm.
All Mazda CX-5 models come with a choice of two new transmissions:
•The six-speed SKYACTIV-DRIVE automatic transmission provides linear acceleration and a direct shift feel similar to a dual clutch transmission.
•The six-speed SKYACTIV-MT manual transmission, with ist compact architecture and enhanced gear structure, delivers the light and crisp shift feel known from the
Environmental Performance
The SKYACTIV-G 2.0 petrol engine with FWD, 6-speed manual transmission and i-stop system targets a mere 6.0 litres of fuel per 100 km (combined) with CO2 emission of 139 g/km.
The SKYACTIV-D 2.2 diesel engine with FWD, 6-speed manual transmission and i-stop system targets just 4.5 litres per 100 km (combined) with CO2 emission of just 119 g/km.
The SKYACTIV-D engine meets Euro Stage 6 emission standards without adopting an expensive NOx after-treatment system.
The SKYACTIV-DRIVE automatic transmission with its new lock-up clutch, achieves lock-up in almost all driving conditions. This reduces transmission slip significantly and contributes to fuel efficiency. It is available for both petrol and diesel engines.
Mazda's idling-stop system, i-stop, is available for the CX-5 with both SKYACTIV-G and -D. It has previously been used only with petrol engine models. With a newly-developed, more advanced control system, the new i-stop shuts off the engine more frequently, helping to further improve real-world fuel economy.
Single-nanotechnology in the catalyst improves exhaust gas after-treatment performance and reduces the amount of precious metals required.
The Mazda CX-5 is one of the lightest and most aerodynamic vehicle in its class, which contributes to its outstanding fuel economy and low CO2 emissions.
Safety Performance
The base of the A-pillars has been optimized to ensure excellent forward visibility on winding roads and at junctions. The side mirrors are mounted on the doors themselves to create a gap between the mirrors and A-pillars through which drivers can check their surroundings.
A host of new, cutting-edge features are available to support the driver's own safety checks and hazard awareness :
Smart City Brake Support (SCBS) is standard for mid and high grade (first in the compact SUV segment) and uses a new radar sensor system to help prevent or reduce impact of front crash accidents at low speed (up to 30 km/h) by automatically braking the vehicle.
Upgraded Rear Vehicle Monitoring System (RVM) that detects cars approaching from behind or driving in the blind spot and warns the driver (now from 30 km/h onwards instead of 60 km/h to support city driving safety).
Lane Departure Warning minimizes the risk of leaving the driving lane unintentionally by employing a camera to detect and judge the position of white lines to then warn the driver of a possible lane departure.
High-Beam Control (HBC) automatically changes between low and high beam during night driving in order to avoid blinding upcoming vehicles.
The lightweight, highly-rigid SKYACTIV-BODY provides excellent collision performance and is conceived to attain top ratings in crash tests around the world.
A multi-load path structure and a front end with a cross-shaped cross-section increases crash energy absorption, further improving safety performance in frontal, side and rear-end collisions.
The anti-whiplash design of the front seats helps to reduce neck injury in the event of a rear-end collision.
There are two impact beams in the front doors. The upper beam has a round cross-section, and the lower beam has a double-ridged cross-section. The lower rear beam also has a double-ridged cross-section, helping to improve strength.
