«I just love the sound of this turbocharged engine
at high revs, plus how planted the chassis feels in corners,» reported Weiner.
At higher revs you can just about kid yourself of some Impreza - style character but it's a bit uncultured even for that, and the popping and crackling overrun in Sport is depressingly artificial — it'll do so even if you're pottering through a village at 2000rpm.
Also, as the engine itself was willing to turn
at higher revs, gearchanges often weren't required until you reached quite ludicrous speeds.
Lift off the accelerator

at high revs, with the exhaust providing an encouragingly sporty soundtrack, it can certainly put a smile on your face.

The 3.8 - liter V - 6 grunts and howls with a dissonance that vibrates the dashboard
at high revs, the shifter is a little balky, and the ride is jarring.
The problem is that the output from the alternator varies dramatically - when the engine is running

at higher revs, with a muscular exhaust note as you take on more speed.
While the M3's normally aspirated, 414 - hp V - 8 packs explosive acceleration
at higher revs — and in absolute terms it's significantly quicker — its comparatively modest 295 pounds - feet of torque means it doesn't get cooking until the tach needle swings past 3,000 rpm.
«The V - 6 is really thrilling
at high revs,» Capparella said after a 1,900 - mile round trip in the 2014 Honda Accord to Ohio and Tennessee, «but also has plenty of torque (252 lb - ft at 4,900 rpm) for highway passing in sixth gear.»

The engine is typically good, with a wide band of torque and a rasping soundtrack, especially
at higher revs.
At 127 lb. - ft., it has the lowest torque figure here, but that's negated, somewhat, by the continuously - variable automatic transmission (CVT) that makes for some smooth progress through the powerband right from 0 r.p.m. Plus, the 141 hp it makes is right in the thick of all of these, although it does have to rev quite high in order to activate i - VTEC variable valve timing, which gives you a bit of a boost
at higher revs.
It does tend to get quite vocal

A high level of lock up prevents automatic up shifts in manual mode
