By moving the engine back by 0.6 inch and lower by 0.5 inch, adding aluminum front fenders, aluminum front suspension knuckles, and narrower tires, this Miata has a lowered polar moment of inertia and is easily coaxed to rotate.

Another corollary of the engine's location is a lowered polar moment of inertia, which means that it rotates more willingly than the two front - engined cars, but it also gets back into line faster if you respond quickly.

Part of this comes from the relatively low polar moment of inertia thanks to the engine being shoved against the firewall.

Subaru says the BRZ has a lower center of gravity than everything but the Porsche Cayman R and 911 GT3, and that its polar moment of inertia is less than the (mid-engine) Porsche Cayman or Mazda RX - 8.

The BRZ's entire engineering mission was a low center of gravity and low polar moment of inertia (meaning that as much as possible of the vehicle's mass is located inside the wheelbase and as low as possible.)

The car has near 50:50 front - rear weight distribution and a low polar moment of inertia, achieved by mounting the engine behind the front axle and the fuel tank ahead of the rear axle.

In general, a longer wheelbase benefits ride quality (because it lowers the frequency of ride motions) and passenger room (by allowing more legroom), but reduces maneuverability by spreading the car's mass over a longer distance, thus raising its polar moment of inertia.

Providing a lightweight, high - strong and stiff structure to which the engine, transmission and double wishbone suspension are attached, the VH platform is designed to concentrate as much mass as possible within the wheelbase for perfect weight distribution, a low polar moment of inertia and a low centre of gravity.

[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG, water vapor, exists in equilibrium with water / ice, would precipitate out if not for the CO2, so acts as a feedback; since the oceans cover so much of the planet, water is a large positive feedback; melting snow and ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River where its driving gradient decreases; the larger slower meanders increase the amplitude and duration of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)
