Come, gather 'round, and we shall explain why.
I'm sure a lot of people here already knew the Lexus IS500 was coming out but I thought I start a thread about the Q50 Red Sport vs Lexus IS500 in terms of competition. I believe they are officially competitors now because the Lexus IS350 was never a competition for the Q50 Red Sport. The Lexus IS350 is over 1 second slower to 60 and to the quarter mile compared to the Q50 Red Sport.
I also believe Lexus decided to call this the IS500 because they knew calling it the IS-F would open it up to M/AMG competition which they know they can't compete; much like the RC-F. Its pretty smart of them to change the name so it markets better.
The excitement and reviews from everyone seems to be positive for the Lexus IS500. I do like the idea the IS500 (IS-F) is back but I also believe Lexus (Toyota) goof'd by giving this car the outdated RC-F V8 instead of the Lexus LS TTV6. People seem to be too hung up on the fact that it has a N/A V8 instead of it actually being a performance car. I would personally have a Turbo'd V6 over a V8 any day.
The Lexus IS500 is going to come into the competition being already slower than the BMW M340i, C43 AMG, and probably slower than the Q50 Red Sport (since there are videos and proof of a Q50 Red Sport beating a RC-F stock per stock). On top of that - it also probably will have a low aftermarket potential in terms of tuning and etc... I felt like they should have gave the Lexus IS500 the Lexus LS TTV6 and make the Lexus IS500 faster than the BMW M340i. This would improve Lexus' image in performance and open the door for a more high powered Lexus IS-F to curb the BMW M3/M4. They missed this boat much like Infiniti missed the Black Series/Black Sport line.
Just my 2 cent.
