Comparing the new 71 R/T 340 I had with auto and the 09 R/T with 6 speed stick and 3.92 gear. The 340 was a very high winding engine . The car was quick and could do 150 on top end . The only thing I didn't like was the steering. It was very touchy or mine was . Brakes were ok for then I guess . Didn't worry about stopping . Don't know how I'd feel about it if I had it to drive now. The 09 feel's like a muscle car , sound and for sure has plenty of power . Good brakes to deal with the extra weight. Great seat's and love the leather and 368 Watt Bose 7 speaker sound system. . Never thought they make anything like it again. Alot went into this new Challenger R/T and it show's.
