That's a decent amount of pep in a lighter car, but not in a heavy mid-sized sedan like the Avalon. I never considered the Avalon a full size sedan when compared to American and German cars (BMW 7 iL series). For Japanese I agree that the Avalon is big, but not really. I always felt the Avalon was a great touring luxury car with fairly soft ride and somewhat aggressive in the power band, but to be honest they are heavy and slow when compared to even smaller economy cars like the Corolla S or any Civic with their small 4 cylinder <160 HP engines. The Avalon would have been a lot more exciting with a 305 or maybe a 350 engine, but you only see those in the Lexus line.
I know the Avalon is not full-sized, but neither was the last Chevy Impala. I like a soft ride, and miss the ‘72 Impala, the ‘70 Olds ‘98, and even the ‘94 Caprice Wagon for room and comfort. I like heavy cars as heavy cars tend to have a smoother ride. For pop I once had a ‘65 Chrysler 300 (lead sled) 2 door hardtop coupe, and the 383 with the four barrel carb and dual exhaust moved the heavy car very quickly. Chrysler used to be good on off the line movement, even in the heavy cars.
That you compare a 750iL to an Avalon (which is less than half the cost) says what anyone needs to know.
