Interesting thread, new to Lexus and only driven an old Rx350 which I now want to buy!
I see it a lot on all the forums I have been on, a mild obsession with BHP, when in reality it's torque that will make the most difference in most driving conditions, some cars don't hit peak BHP until right at the end of the rev range in a gear the car hardly spends any time in. I've paid for decent maps on cars that don't change the BHP at all, but adjust the torque delivery.
An observation on the ES is that 220nm is feeble, I can only assume that's because the main engine is naturally aspirated and no turbo, so it will definitely feel slow against much much more powerful rivals (especially diesels). Couple that with a CVT gearbox and the associated rubber band effect (although I'm sure the e-cvt is more advanced that the ones I have spent time in) then you'll get a lot of acceleration noise and not much happening. Again, all relative I guess, I assume most buyers of a lexus aren't looking to hoon around, in which case it's not that relevant.
For comparison, I had a great time in a ford sportka 1.6 N/A which had about 92bhp and it revved freely and sounded fantastic, with a lovely snickety gearbox. It was also the same speed to 60 as the Lexus we are talking about due to the weight and adventurous gearing.
Anyway, great thread, some interesting comments, I love and appreciate all cars.
