Not exact matches
The overall gearbox ratios have been
reduced compared to those in the standard 911, meaning that the GT3 reaches its
top speed in seventh
gear rather than sixth.
The other upshots are shorter initial
gears for better acceleration feel and taller
top gears for better highway fuel economy and
reduced engine noise.
What that means is that the ZF - 9HP's
top gear is «taller», spinning the engine at lower revs on the highway to
reduce fuel consumption.
Perhaps more importantly, more speeds in the transmission allow automakers to
gear the
top ratio «taller» — tech talk for the engine turning more slowly — and, again, rpm
reduced is fuel conserved.
The higher
top gear not only
reduces fuel consumption but the lower engine revs improve comfort and
reduce noise when cruising at a sustained speed.
With a wide 7.39 overall
gear ratio spread and lower numerical
top gear ratio, the transmission also improves efficiency by
reducing engine revolutions at highway speeds.
The wider overall ratio enables a lower numerical
top gear ratio — an attribute that
reduces engine speed on the highway, which contributes to greater fuel efficiency than a comparable eight - speed transmission.
You get a five - speed gearbox in SCe 115 petrols and a six - speed in the TCe 125 petrol and dCi 110 diesel — the six - speed is considerably more relaxed at motorway speeds, its high
top gear ratio
reduces engine revs when cruising.
It's now even better thanks to taller second and
top gear ratios in the LC70's sole five - speed manual transmission, which extracts more of the significant torque available at low speeds and
reduces engine speed to less than 2000rpm in
top at 100km / h.
