small cars more fuel-efficient now than at any time in their
small cars that are more fuel-efficient than they were at any time in their
small cars that are more fuel-efficient than those at any other time in
more fuel-efficient small cars than those at any other time in their
more fuel-efficient small cars now than at any time in
请看讲解视频
any time 不等于 any other time .只能用any other time,否则就把now也包括进去了。
此外，A中核心比较对象是make efficient这件事情，所以要比较对等就得后面也是一件事情。DE中比较的是现在比以前可以产更多汽车，不符合题意，要比较的话也只需要用now 和in any other time 作比较就可以了
