2020 Mazda MX-5 Miata Suspension Deep Dive

Full disclosure: I’m a longtime Miata fan. And by longtime I mean since mid-1989, the year I obtained, through a series of fortunate connections, one of the three original Chicago auto show display cars. But this was no blatant attempt to butter up a journalist – I barely knew how to spell the word. At the time I worked for the Department of Defense and was racing SCCA showroom stock on the side. It was destined to be a racecar. I was assured itÂ’d be quick, but doubts surfaced when I arrived at MazdaÂ’s dealer training center to pick it up. “Oh, itÂ’s that cute Elan-looking thing,” I probably said. But my mind was utterly changed when I eyeballed its double-wishbone suspension and other cleverly engineered features hiding beneath its skin. In subsequent years of racing – and eventually restoring – that car, I spent uncountable hours being impressed by it. I can safely say that the new ND Miata (2016 - present) is the best yet. ItÂ’s lighter than it has been in 20 years, and thatÂ’s some trick considering the relentless march of safety requirements and expected convenience features. This car is actually 1.3 inches shorter from nose to tail than my NA Miata, but itÂ’s also 2.4 inches wider and rolls on a wheelbase that is 1.7 inches longer. But it is the suspension that has always made the Miata great. This look under the skin of a 2020 Mazda MX-5 shows why the ND is the best Miata in that arena, too. The fact that this is an RF model doesnÂ’t much matter one way or the other.   As it was the first time I laid eyes on one, things got off to a promising start as soon as I pulled a wheel off. ItÂ’s clear that this is no mere strut suspension, as we can see a coil-over shock and glimpses of aluminum.   The apparent stars of the show are the A-shaped upper wishbone (green arrow) and the L-shaped lower wishbone (white). Miatas have used this layout from Day One, but aluminum didnÂ’t enter the picture until the NC generation.   For 2020, Bilstein monotube shocks (green) come on the Club and Grand Touring models with a manual transmission. This setup was part of the GT-S option package in 2019. The standard shocks are also monotubes, but theyÂ’re not Bilsteins and theyÂ’re tuned a bit softer. The upper control arm (yellow) is mounted low down such that its ball joint (white) resides within the barrel of the front wheel.

Our Mazda MX-5 Miata has the best engine bay in the business

One of the things that's really disappointing about modern cars is how they all hide their technology under a proverbial bushel. You pop the hood, and nine times out of 10, you're faced with some amount of black plastic hiding the functional bits. On some cars the plastic covers the bare minimum to have a "presentable" engine. Others have every tank, hose, wire and screw buried under a layer of smooth plastic. Few exemplify this practice better than engine bay of the current Lexus LS 460, seen below. If Lexus was this embarrassed about its engine, maybe it should have simply bolted the hood shut. However, like with weight gain and power creep, our fourth-generation Mazda MX-5 Miata bucks the plastic trend. Lift the aluminum hood of the little roadster, and you travel back in time more than a decade. (See the gallery up top.) Only one bit of decorative plastic is in sight, and it proclaims the car's Skyactiv technology and hides some of the wires leading to the ignition coils. Otherwise, nothing else is obscured. The shock tower braces, manifolds, battery terminals, the whole shebang is all right there for you to see. What's particularly amazing is that it all looks good. Even in some cars that eschew plastic covers, it's no guarantee of an attractive engine bay. We just had a new Honda Civic Sport hatchback (seen immediately above), and while it doesn't sport a plastic engine cover, you can see from the photo that it's not particularly attractive with tubes and cables snaking every which way. But in the Miata, the hoses and wires are kept to a minimum, and the ones that are there are arranged in a way that isn't haphazard or tangled. Then, in the middle, there's the clean, simple aluminum cam cover as the gleaming centerpiece, similar to those of the first- and second-generation cars. As the owner of a '99 Miata, this detail in particular gives me the warm fuzzies. The fully exposed engine bay fits with the Miata's personality. The car is very straightforward, it features just the absolute minimum of style and comfort additions, and is highly accessible. I would say the Miata's engine bay is the window to its soul, if driving it didn't offer a clearer picture. Related Video:

Five vehicles named Top Safety Pick+ including new Civic, MKZ

In an attempt to help push vehicle safety to a higher level, the Insurance Institute for Highway Safety created a stricter Top Safety Pick+ rating last year, which incorporates a brutal small overlap test and requires cars to get Good ratings in four out of the five categories (and no less than Acceptable in the fifth). Joining the list of the safest cars of 2013, the 2013 Volvo XC60, Lincoln MKZ, Honda Civic (sedan and coupe) and the 2014 Mazda6 have all received the coveted TSP+ rating.
The Mazda6 and Lincoln MKZ have both been completely redesigned, and both received Acceptable ratings in the small overlap test. The Honda Civic, coming off its emergency refresh for 2013, is the first small car to be subjected to the small overlap test, and IIHS says that one of the car's many upgrades includes a stiffer front structure allowing it to receive Good ratings in all categories. Similarly, the XC60 gets all Good ratings thanks to, according to IIHS, Volvo updating the airbag software allowing the side airbags to inflate during the small overlap test.
The 2014 Subaru Forester has not yet been subjected to the small overlap test, so it must make do with just a Top Safety Pick rating until the IIHS tests small utility vehicles, which is expected to happen later in the spring.
