As well, since the alternator is disconnected when the engine is under power, full - throttle acceleration should get a boost (though that may be offset by
a taller axle ratio on the i - ELOOP versions).
Not exact matches
Even though this Miata's six - speed manual transmission has a fairly
tall ratio in sixth gear for highway cruising, the rear
axle's final - drive
ratio is fairly short to enhance acceleration, so the Miata's 2.0 - liter inline - 4 engine spins above 3000 rpm at ordinary cruising speed and close to 4000 rpm if you're brave with speed limits.
Both provide a
tall cruising gear for good highway mileage (there are three
axle ratios from which to choose).
You'll pay an additional $ 2,650 for that transmission, which also includes a 3.42 -
ratio rear
axle that's slightly
taller than the standard
ratio for better highway fuel economy — save your hate mail, I know I accidentally called it a lower
ratio in the video — and $ 7,795 for the extra power.
