Is The 2007-2013 (2IS Generation) IS 350 Faster Than The 2015 RC 350 F Sport?
I have a 2009 IS 350 which I love, it's fast and responsive when I hit the skinny pedal and feels like a torque monster. This weekend I went and test drove a RC 350 F Sport RWD and felt it was considerably slower launching off the line then my 2009 IS 350.
Now I know both cars have the exact same engine so this leaves me to believe that the only difference is the weight since both engines have a 306hp 3.5L V6, or possibly the transmission since they switched over to an 8-speed tranny on the F Sport.
If my research was correct, the RC 350 F Sport weighs 3748 lbs while the IS 350 weighs 3,527 lb which makes the RC 350 221 lbs heavier.
0-60 times I found were different as well:
2nd Gen IS 350 0-60: 5.6 seconds
1st Gen RC 350 0-60: 5.8 seconds
Thoughts from some of the more experienced folks here?

2IS Is lighter so will be faster in 0-60 and 1/4. However on a track the RC should beat it, the 2IS chassis, suspension, transmission logic were much to be desired. The 3IS IS350 F Sport nearly matched the laptime of the 08 ISF on C&D Lightning Lap. It's obvious it was due to the chassis and suspension tuning.
I drove an RC350 F Sport at the Houston Asphalt Up event. The chassis was very solid even moreso than my 3IS. It felt very nimble too, it might have had the rear wheel steering and its 3" shorter wheelbase than the 3IS.

I'm really disappointed that they are using the same engine on the 350 and F as the previous generation IS350/ISF. The least they could have done was to squeeze a little more performance out of the engine if they were gonna reuse it, especially if they were gonna add more weight to it. SMFH.

i have a few mods on my 2nd gen IS350 and you're right..
if you're talking about off the line the 3rd gen IS350s and RC350 which i both test drove recently in the last few months feel a lot slower off the line.
i don't actually know if it's slower though, it just definitely felt a lot less pull when you floor it

^ interesting... is this even with the 3IS in Sport + ? I did find it interesting that in my 2IS if you put the car in PWR on the left, the car seems to move alot quicker, but never ridden or driven a 3IS

yeah i pretty much drove the 3IS and RC in sport+ most of the test drive. i think the speeds were pretty much the same as my 2IS it just didn't "feel" fast off the line.

Well I'm glad I'm not the only one who thought the same........the only benefit I see with them keeping the same engine is that all of the aftermarket parts from the 2IS/3IS should bolt onto the RC then so maybe I can bump some HP/TQ with some bolt on modifications if I end up buying one in the future.

There aren't too many bolt on mods for the 350 engine, especially with significantly higher HP/TQ. Not worth voiding warranty. I think the reason Lexus stays away from turbos is because they aren't too reliable. Cousin has a 335is and it's always at the dealer for problems. Have a A4 2.0t at home with higher mileage and it's having a lot of problems with oil consumption now because of the turbos. Kinda surprised Lexus came out with the turbo-4 for the NX. Will see how reliable it is in a few years...maybe Lexus worked its magic on it. I wonder if supercharging is more reliable???

Yes it will be slower. It has the exact same engine but its a few hundred pounds heavy. You can also factor in you drove a new car with a engine that hasn't been broken into yet. After the break in period (or after a few thousand miles) the engine will open up and accelerate faster.
Lexus isn't focusing on fast vehicles; they are focusing on cars that are fun to drive. A car that obeys the driver's every command.
