Mazda CX-5 Refines Handling with MX-5-Inspired Chassis Tuning
Mazda has focused on enhancing the driving characteristics of its CX-5 SUV, drawing inspiration from the renowned handling of the Mazda MX-5 Miata. Recent adjustments to the suspension and chassis aim to improve both comfort and agility, building upon the CX-5’s reputation for engaging driving dynamics within the SUV segment.
Skyactiv Technology and the CX-5’s Evolution
The Mazda CX-5 was the first model built on Mazda’s modular Skyactiv technology platform. It quickly distinguished itself with careful chassis tuning and driving characteristics atypical for an SUV. Following the second generation in 2016, the current third generation arrived last year, further refining the driving experience. The CX-5’s design dates back to 2014, with ongoing improvements to maintain its competitive edge.
Bridging the Gap: MX-5 Influence on CX-5 Tuning
Despite their differing concepts – the MX-5 being a classic front-engine, rear-wheel-drive roadster with a Power Plant Frame (PPF) and the CX-5 utilizing a transverse engine and front or all-wheel drive – Mazda engineers looked to the MX-5 for insights into achieving a more refined ride. The focus was primarily on suspension adjustments.
Advanced Shock Absorber Design
Mazda invested in a more advanced shock absorber design, coupled with changes to spring stiffness. According to Ruben Archilla, a research and development manager at Mazda, the goal wasn’t simply to alter chassis characteristics but to “make it simply better.”
The new shock absorbers feature a larger piston diameter and modified throttle valves, reducing resistance to fluid flow and minimizing friction. This allows for better damping at low speeds, enhancing comfort without compromising handling during cornering.
Spring Stiffness and Damping Force
The stiffness of the springs has been reduced, resulting in a more linear damping force. This means the shock absorbers provide better damping with small wheel movements for improved comfort, while remaining firm enough for confident handling during aggressive turns. This approach mirrors two-stage shock absorbers, similar to Monroe’s Sensa-Trac technology from the 1990s.
MX-5 Suspension as a Benchmark
The inspiration from the MX-5 is particularly evident in the softer spring characteristics. Archilla noted that the MX-5 has the lowest natural frequency of all Mazda cars, contributing to its comfortable yet responsive ride.
G-Vectoring Control and All-Wheel Drive Enhancements
Mazda also refined its G-Vectoring Control system, which reduces engine torque when entering a corner to shift weight to the front wheels, increasing grip. Improvements were also made to the all-wheel-drive system to behave more like a permanent four-wheel-drive system, enhancing stability in straight-line driving.
Future Developments
Mazda continues to innovate with its Skyactiv technology. The CX-5 is slated to receive a full hybrid powertrain in 2027, featuring the new Skyactiv-Z engine, which prioritizes real-world efficiency and ultra-lean combustion techniques. The next-generation MX-5 will also utilize the 2.5L Skyactiv-Z engine, remaining naturally aspirated and offering a manual gearbox.
