That's
excellent news
for around - town
drivability, but it comes with a price: Whereas previous Civic Si models sounded and felt special because they revved sky - high like a motorcycle, this car's engine checks out at humdrum 6,500 rpm.
The big V12 now makes 580 horsepower, up from 568, courtesy of larger intake manifolds, and the
excellent eight - speed automatic transmission has been recalibrated
for quicker shifts and better low - speed
drivability, not that the Vanquish needed improvement in these areas.
