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 an aluminum power plant frame ppf unites engine transmission and differential into a rigid unit this structural backbone helps ensure that maximum power reaches the rear wheels and helps eliminate drivetrain twist and acceleration delays true to its sports-car heritage a short-throw close-ratio 5-speed manual gearbox is standard on the mx-5 miata also available are a slick-shifting 6-speed manual and a 6-speed sport at automatic transmission the sport at s competition-inspired design allows you to manually shift gears via the shifter or steering-wheel-mounted paddles a b c engine torque lb-ft 150 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 130 new 2.0-liter engine 110 previous 1.8-liter engine 90 now in its third generation this mx-5 miata boasts a larger more powerful 166-hp 2.0-liter dohc 16-valve engine endowed with a higher and broader torque curve especially in the mid-rpm range it generates an abundance of more useable power variable valve timing and variable induction are also utilized to maximize low-end torque and high-rpm power its advanced design even incorporates an electronic throttle and electronically controlled port fuel injection to promote a more linear response and superb acceleration 7000 70 1000 2000 3000 4000 5000 6000 engine speed rpm
