KBB Editor's Overview

By Editorial Staff

The 2010 Mazda RX-8 is one of those cars that can generate strong emotions. Owners love its neutral handling, unique four-door coupe design and lightweight rotary engine. Those same owners, however, often complain about the car's sometimes disappointing fuel economy and noticeable shortage of low-end torque. If you can overlook those eccentricities, and the fact that, when equipped with the automatic transmission, the engine loses 20 horsepower, the RX-8 makes a fine sports car, one that lets you take along three other adults and a bit of luggage. The RX-8's sub-$30,000 price tag, stunning interior detail and long list of standard and available features are just icing on the cake.


You'll Like This Car If...

If you love the nimble, responsive handling of the Miata, but want something faster and with room for four adults, the 2010 Mazda RX-8 may win you over.

You May Not Like This Car If...

If you're looking for a low-involvement sports car (which is, to a certain extent, an unreasonable expectation), the 2010 Mazda RX-8's rotary engine, with its occasional oil and fuel consumption issues and short-at-the-bottom torque curve, may not be to your liking. The compact rotary engine delivers its torque high in the rpm band, meaning you have to run the revs high when passing or accelerating.

What's New for 2010

The 2010 RX-8 receives a revised front and rear fascia as well as a simplification of the model lineup. The Touring trim has been dropped, as have the Premium Package options. A sunroof is now standard on the Grand Touring trim and Mazda has made significant improvements to the rotary engine aimed at minimizing oil consumption.

Driving It

Driving Impressions

At idle, a slight, distinctive vibration is the telltale sign a rotary engine lurks beneath the hood; it's not annoying in any way and actually makes the car feel almost alive. Slip it into first gear and you'll feel the pull of the 232-horsepower RENESIS engine, slowly at first, but then increasingly faster once the tach climbs past 2000 rpm. With a 9000-rpm redline, all you have to do is keep the engine between 4000 and 6000 rpm and you'll always find more than enough power on tap for quick bursts of acceleration. The six-speed shifter requires only the slightest movement to change gears, and the clutch engages so smoothly it's easy to execute neat, clean shifts. The electrically controlled steering is neutral and extremely precise in both its execution and feedback.

Vehicle Details


Slip inside the 2010 Mazda RX-8 and immediately the quality of the materials and the depth of detail will impress you. A combination of suede-like fabric and ribbed cloth inserts covers the excellent sport bucket seats, and the driver's seat features a height-adjustable cushion. Although you can opt for full leather seating, it won't have the same Velcro-like grip on your clothing of the standard seats, which is a nice attribute when hurrying around tight curves. The instrument cluster is housed in a dash-mounted binnacle that includes a center-mounted tachometer with an inset digital speedometer. Why Mazda chose this design is a bit of a mystery, as a nice analog speedometer could easily have been placed on either side of the tachometer.


The 2010 Mazda RX-8's styling will probably not appeal to everyone. Its bulging wheel arches, unusual half-doors and low profile give it a look that either draws you in or leaves you cold. The RX-8 forgoes a hatchback design in favor of a usable trunk, a nice feature if this is your only car, and it also tends to look different depending upon the paint color, with brighter colors seeming to accentuate the car's crisp lines.

Notable Standard Equipment

The RX-8's standard equipment includes a 232-horsepower rotary engine (212 horsepower with the automatic), six-speed manual transmission, four-wheel anti-lock disc brakes (ABS), rear defroster, four cup holders, rear console, keyless entry, dual power mirrors, AM/FM stereo with CD, side-impact and side-curtain airbags, rear-seat pass-through, cruise control, sport suspension, tire pressure monitor, power windows, power locks and a tilt-wheel with touch controls. Grand Touring models gain a power moonroof, heated leather front seats, rain sensing wipers, traction and stability control, auto on/off HID headlamps, automatic air conditioning, torque-sensing limited slip differential, heated side mirrors, power driver's seat and a 300-watt, nine speaker Bose Centerpoint audio system with six-disc CD changer. The R3 adds to the Sport's standard equipment a sport tuned suspension, side sills, fog lights, 19-inch wheels surrounded by performance rubber and Recaro sport seats.

Notable Optional Equipment

This year's revised packaging leaves very little on the options list. The Grand Touring model can be equipped with a DVD navigation system, while Sport and R3 trims can have SIRIUS Satellite Radio installed.

Under the Hood

The RENESIS rotary engine displaces a mere 1.3 liters by rotary measurement formulas, yet produces an impressive 232 horsepower (212 with the automatic). A maximum torque rating of 159 pound-feet is not much to brag about, but with a 9000-rpm redline (7500-rpm with the automatic transmission), you can milk every ounce of the engine's power before upshifting. What makes the rotary engine unique is its simple architecture. Instead of pistons, valves, camshafts, connecting rods and a crankshaft, the rotary requires only an output shaft surrounded by triangular-shaped rotors housed in chambers that are shaped somewhat like ovals with pinched middles. The rotary is therefore mechanically very simple, has minimal moving parts and is quite small.

1.3-liter RENESIS 2-rotor rotary
232 horsepower @ 8500 rpm (manual)
212 horsepower @ 7500 rpm (automatic)
159 lb.-ft. of torque at 5500 rpm
EPA city/highway fuel economy: 16/22 (manual), 16/23 (automatic)


Pricing Notes

The RX-8 Sport with either the manual transmission or six-speed automatic has a Manufacturer's Suggested Retail Price (MSRP) starting just over $27,000. The Grand Touring with automatic tops out around $35,000. The R3 starts around $33,000 and has only a few dealer-installed options to offer. To see what the RX-8 is selling for in your area be sure to check the Fair Purchase Price page. As sports cars go, the 2010 Mazda RX-8 holds average resale value, on par with the Mitsubishi Eclipse but well below the Audi TT, Ford Mustang and Nissan 370Z Coupe.
