it s all about generating more power per pound weight is the enemy of every true sports car so mazda engineers implemented a radical weight-saving gram strategy to make certain that every critical component in this 3rd-generation mx-5 miata was as light and strong as possible which is why everything from its powerful 166-hp engine and handsome hood to its sleek trunk lid and rear brake calipers are all crafted from aluminum and why its ultrarigid body structure makes such generous use of high-tension steel light and strong it helps increase torsional stiffness 47 and flex stiffness 22 compared to the previous generation mx-5 miata it also helps improve virtually every aspect of the car s dynamic performance including power delivery steering handling and braking which is why it s more agile and more responsive and in dramatic contrast to some roadsters hastily assembled from shared off-the-shelf parts the mx-5 miata is a true purpose-built design which readily explains why it s nearly 400 pounds lighter than some competitors and most important of all why the mazda mx-5 miata is able to forge such a unique intuitive feeling of oneness between car and driver based on a comparison of model year 2006 roadsters a b c a the mx-5 miata utilizes an ultralight flywheel to enhance the engine s free-revving performance and improve its responsiveness b friction-reducing molybdenum-coated pistons plus a high-compression ratio help the current mx-5 miata engine generate 17 more horsepower than the previous generation s powerplant c a limited-slip differential and dynamic stability control with traction control system are available on select mx-5 miata models.
