Any review you read of the RCF expecially if that review is between RCF vs M4. it just a contridicting mess, Latest is in "Car Magazine". First they like the fact lexus stayed with a N/A V8, then they say this V8 is slow "no guys for a N/A V8 engine it very powerfull rather it the car that heavy". any N/A engine will always struggle against the force fed engine but the N/A offers better driveablelity. So M4 wins on the treck on the road the RCF destroys the M4, now they praise the RCF it makes the difference it revs like it want to reach 10 000rpm. take note the M4 only won on the treck the rest RCF is just better. better interior, better traction, better ride yet still M4 wins
