Twincharging is therefore desirable for small - displacement motors (such as VW's 1.4 TSI), especially those with a large operating rpm, since they can take advantage of an artificially broad torque band over a large speed range. (en.m.wikipedia.org)
The six - speed automatic was smooth in operation, and its many ratios and the engine's broad torque band ensure that the correct gear for the situation is chosen more often than not, which is good, as there is no manual gear selection; the driver gets to choose between D and L only. (cnet.com)
