Q & A

What are some of the main challenges Mazda faces in continuing to produce the MX-5/Miata roadster?
-Key challenges include increasingly strict safety and emissions regulations, the high cost of electrification/hybridization, the need to keep the car lightweight, and the small production volumes.
Why is Mazda so committed to keeping the MX-5/Miata lightweight?
-Light weight is critical to preserve the pure sports car driving experience of the MX-5/Miata. Adding too much weight from batteries or safety features would ruin the car's fun-to-drive character.
What markets are most important for MX-5/Miata sales?
-The biggest markets are the US, Japan, and Europe. Together they account for about 97% of sales.
How much longer can Mazda feasibly keep producing the gas-powered MX-5/Miata?
-Maybe around 10 more years. Mazda wants to keep the current generation going as long as possible before full electrification.
What percentage of MX-5/Miata buyers choose the manual transmission?
-Around 70% in Japan. Roughly 50% in the US market as well.
How has Mazda improved the electronics and connectivity systems on the latest MX-5/Miata?
-They completely updated the hardware and communications protocols to make the car much more resistant to cyber attacks.
Why did Mazda switch the headlights and taillights to LEDs?
-Partly for styling, but also because the new electronics could not control the old headlight motors.
How profitable is the MX-5/Miata for Mazda?
-Likely not hugely profitable given the development costs and low volumes. But Mazda sees it as an important car for the brand.
Does Mazda plan to sell the MX-5/Miata in China?
-Not currently. Export restrictions make it unfeasible, and volumes would be very low anyway.
Could Mazda turn to crowdfunding to help support continued MX-5/Miata development?
-It's possible, since the car is sold at a relatively low price despite the high development costs. Fans might donate to keep it going.

Keywords

💡Cyber security

The video discusses cyber security threats like hacking that automakers need to defend against, especially for connected and autonomous vehicles. They explain how cyber attacks could manipulate things like vehicle speed, so security has become a major focus in development.

💡Safety regulations

Stricter safety regulations are making sports cars difficult to develop. Standards for crash protection, child seats, etc. are getting harder to meet while maintaining lightweight sports car qualities.

💡Platform sharing

The MCX-60 platform is shared across vehicles to save costs. But issues like non-functional headlamps revealed the challenges of platform sharing between very different vehicles.

💡Lightweighting

Keeping the lightweight, open-top sports car feeling is an obsession for Mazda. But new features for safety, emissions, etc. make it harder to reduce weight with each generation.

💡Manual transmission

High demand for manual gearboxes allows Mazda to stand out, but their prevalence is declining globally. Preserving them is another challenge Mazda faces.
