  • Mazda is about to sell its first battery electric vehicle, the MX-30 crossover.

  • I’ve said more than once that not everyone needs 200-300 miles of range in their EV, but will the 100-mile range of the MX-30 be too much of a stumbling block for US customers? Mazda’s only looking for 560 of them to start.

  • Despite sharing the same dimensions as the CX-30 crossover, the MX-30 feels much smaller inside. Rear legroom has lost more than six inches because of the battery pack.

  • I find the MX-30 ungainly to look at from more than one angle.

  • The interior color palette is almost Volvo-like. The seats are comfortable, which is important in a commuter car.

  • Did you know that, before Mazda built vehicles, it was a cork producer? Now it uses cork as a lightweight and sustainable trim material.

  • The floating console is for the drive selector and infotainment controls.

  • For occasional use only?

  • There is 21 cubic feet (595 L) of cargo storage.

  • An exploded view of the MX-30 battery pack.

  • A look at the MX-30 chassis from underneath. The battery frame is in black.

  • A cutaway of the MX-30 chassis.

  • There’s room under the hood for a range extender engine.

  • The MX-30 will charge at 240V AC in less than three hours, or in 36 minutes to 80 percent at 50 kW DC.

  • The problem with the MX-30 isn’t its range, it’s that it’s just not fun to drive.

  • Is the real MX-30 customer the Mazda engineer who gets real-world data back from the cars? Or is the customer the California Air Resources Board’s zero emissions vehicle mandate?

IRVINE, Calif.—It’s fair to say that Mazda has some work ahead of it with regard to electrification. The Japanese automaker has repeatedly impressed us with its keen understanding of vehicle dynamics and attention to details. But Mazda is only just bringing its 1st-generation battery electric vehicle—the MX-30 compact crossover—to market at a time when other carmakers are on their fifth.

It would be easy to dismiss the Mazda MX-30 just based on the numbers. The 100-mile (160 km) range will be the biggest hurdle for people to get over; that would have been a hard sell in 2014, let alone now in 2021. Then there’s the fact that Mazda only plans to import 560 MX-30s for now, all bound for California. This is not an EV for the masses, something Mazda’s PR people were upfront about. They’re openly describing the $33,470 (before federal tax credits) EV as a “commuter car.”

And yet Mazda is the car company that built a crossover that’s more fun to drive than most hot hatches. It has also churned out more than a million MX-5 Miatas. Which is why I went to California last week to find out whether the MX-30 is a rare Mazda misstep or if the boffins from Hiroshima had a surprise in store after all.

The MX-30 uses Mazda’s Skyactiv chassis architecture, which is also used by the CX-30 crossover. In fact, the MX-30 is nearly identical in size to the CX-30: both crossovers have the same 104.4-inch (2,652 mm) wheelbase, and they share their lengths (173 inches/4,394 mm) and widths (71 inches/1,803 mm). At 61.5 inches (1,562 mm), however, the electric MX-30 is a fraction shorter.

Those numbers are actually a little surprising. In my experience, the MX-30 feels smaller, particularly on the inside. The suicide doors—I’m sure Mazda would prefer we call them “freestyle doors”—are reminiscent of the BMW i3, and our vehicle included a cramped rear seat that’s more suitable for cargo storage than carrying two full-size passengers.

Technology The interior is a bit quirky. But only a bit.

The MX-30 has a slightly more whimsical interior than we’ve come to expect from Mazda. A thin layer of cork is used as a surface treatment in places—a nod to Mazda’s origin as a cork manufacturer before turning to vehicles. Cork is used on the back of the interior door handles as well as lining the center console, which conceals its pair of cup holders with flip-up lids.

Floating above, another panel sticks out from the dash with the rotary controller and buttons for the infotainment, as well as the drive selector. Ahead of that is a touchscreen for the climate controls—the non-touchscreen infotainment screen is recessed into the dashboard up above, in the driver’s sight line. Underneath the drive selector and infotainment control panel, you’ll find a pair of USB-A ports for connecting devices and a 150 W, 110 V AC socket.

The use of cork gives you something interesting to feel, particularly when you’re opening or closing the door from the inside. But it’s hard to escape the impression that Mazda’s designers and engineers were fighting a critical battle to keep the MX-30’s weight down.

That’s for the same reason as the missing interior space: the need to package a 640 lb (310 kg) 35.5 kWh lithium-ion battery pack. In the end, the MX-30’s curb weight is 3,655 lb (1,658 kg). Charging it should take under three hours with a level 2 AC charger or 36 minutes to 80 percent on a 50 kW DC charger.

In time, Mazda will build plug-in hybrid MX-30s, as well as true series hybrid MX-30s that use a rotary engine as a range-extender. But for now, we’re just getting (560) BEV MX-30s here in the US. These use a 143 hp (107 kW), 200 lb-ft (271 Nm) electric motor that powers the front wheels.

In our predrive briefing, Mazda pointed out that the battery pack does mean the MX-30 has a rear-biased weight distribution, which means less load is on the front tires during corner and less lateral weight transfer. And the pack contributes to a body that’s 45 percent more torsionally rigid than the CX-30.

Mazda also told us that its G-vectoring control system (which uses tiny amounts of torque to control weight transfer during turn-in) works faster than ever since it has finer and faster control over an electric motor’s output than an internal combustion engine. Also, the solid-mounted electric motor allows the Mazda to fit tires with stiffer sidewalls, because it doesn’t have to worry about filtering out vibrations from the road that could interfere with an internal combustion engine.

Technology Where’s the zoom-zoom?

I have already mentioned that Mazda knows how to build normal cars that reward drivers; within the first five minutes of driving a CX-30, you’re aware something special is at work, possibly some kind of magic. Unfortunately, I got none of that from the MX-30. The electric motor is torque-y enough that it will spin its low rolling resistance front tires if you are too heavy with your right foot, but there’s a numbness to the driving experience that was frankly disappointing.

The MX-30 has a single drive mode—no messing with Eco or Sport modes here. But it also has increasing (or decreasing) stages of lift-off regenerative braking, which you control via paddles on the steering wheel. The left paddle increases lift-off regen; the right paddle decreases it. At high or max, you can easily one-pedal drive, and when you’re in its minimum setting, the MX-30 allows you to coast when you lift the throttle.

The springs and dampers coped fine with sharp shocks like expansion joints, but long-duration road scars were transmitted into the cabin, where they found ways to vibrate bits of trim here and there. The result is a driving experience that’s adequate for commuting but doesn’t make you want to take the long, twisty way home just for fun. Which you probably wouldn’t do anyway if it involves much of a detour.

Our drive route was a little over 60 miles of mixed canyon, suburb, town, and freeway. I averaged 3.8 miles/kWh, which was just slightly more than 1 mile for each percent of charge. Mazda research says plenty of commuters drive less than 30 miles (48 km) a day, which is easily handled by the MX-30 range. But I’m not sure that’s the real customer for this EV.

I mentioned earlier that the MX-30 reminded me of the BMW i3 in more than just the short range and suicide doors. BMW used the i3 (and the Mini e before it) as a way to get some real-world data on its then-nascent EV technology, and Mazda needs all the EV data it can get. So it’s possible that the MX-30 is a subsidized engineering exercise meant to inform Mazda’s next BEVs. Three Mazda BEVs are due between 2023-2025.

A more cynical, albeit more likely alternative was offered by a colleague: is 560 the exact number of zero-emission cars that Mazda has to sell in California to avoid the wrath of the Golden State’s Air Resources Board?
