Unless they had him drive several times and took the average in each mode, how do they account for different driver response in each attempt? A human driver can't drive (accelerate/brake/steer) in exactly the same way 3 times in a row. Even a slight change in when the driver brakes or identifying the apex at a turn will cause that difference

1. Stig, the racer for that show... never makes a mistake.
2. Most professional racers can keep very consistent lap times when NOT competing.
3. If you are the only car on the track which you've driven for 15 seasons... the times become even more consistent.


But all joking aside...
The point I'm making is that when you are full throttling, it pretty much doesn't matter. I'm not saying that Eco faster.

Theoretically, yes, eco mode should be used in the city with frequent accelaration, but I think it a real world driving it is the opposite. On my first 900 miles as of today Eco vs. normal in city is the same, but definitely a difference in highway. always, it's your driving habit, too.

Understood

plugged in my ODB2 Bluetooth module and onto my phone using torque. Torque has a built in 0-60 that reads off the ECU so... pretty accurate, better than GPS ones...

Turned off traction and took it from 0-60 and sport and normal. i wasn't at the track so i usually do this on the way to work...

i've done it twice so far.

Normal: 6.67 (Raining) traction off
Sport: 6.7 (Colder dry day) traction on

I didn't rev up for proper launch on purpose, just trying to get a comparison...

jucytec

did it again this morning, 6.1 on sport by revving to 1.5
would've gotten lower as traction did kick in during launch

WOT is WOT no matter which mode you are using. So I am of the opinion that once you are at WOT, performance is the same. From a standing start, however, the performance modes may get you to WOT sooner.

jucytec

What What?! LoL

Its going to be the same. WOT is WOT.

Should be the other way around because in the city is when you have the starting and stopping which kills the gas. on teh highway its just a constant flow

Fuel economy was the same for me between ECO and NORMAL during combined city/hwy driving. I never use ECO mode now because the car just feels too sluggish to me.

raytseng

not sure what the OP's point is. even if we grant the OP's statement as true, the car isn't just a binary switch with WOT or no throttle. The stuff in between matters. So it's not just the same crap.

Unless you really do just drive like a switch and only go between 100% WOT and 0 Throttle.

I see a definite bump in MPG when using ECO in the city but not on the highway, so the manual is correct. It is under frequent goes and stops that it makes a difference.

What EXACTLY happens when i switch to Sport+ mode?
Do i have special shocks that can be stiffened up with air/fluid change?

How is the steering "tightened up". is there a similar steering damper that is adjustable?

PirelliRC

most of what you outlined is done electronically now, not hydraulic. The steering for example is electrical, that how they can stiffen it up, same with the suspension.

as far as the 0-60 you might be correct on that one but there is a HUGE difference between modes. Mine is a 2014 GS 350 RWD and when i put it in Sport mode the steering wheel stiffens up dramatically, the throttle response is much more precise. You barely touch it and it flies.

I willing to bet you will be few tenths of a second faster in Sport mode than ECO because it holds in gear longer and plus a 0-60 you talking about 5.5 secs. You can get a WAY better launch on Sport mode than ECO so i think it will slightly faster. i never drive on ECO, it sucks. Normal is perfect, if i want more speed and better cornering i put in Sport.
