Have yet to jack rabbit off the traffic lights yet.

 

Firm pressure down accelerator midway is enough to get ahead of most vehicle in the starting lineup (except for that Harrier NA that does 0-100 in 6sec :D and now even more so for the new Turbo).

 

No kick in the butt of my prev 2.5t legacy, yet torque comes so early and flat throughout the useful rpm that the pull is felt from 1,200rpm..which is not too far from idle rpm of 800rpm.

 

Once again, compare to my other Saab 2.0t LPT with hirschprung ECU flash up(something like that :D), the saab feels lethargic from step off. The torque comes in later than the merc and not as linear. 

 

To answer your question, yes, the power delivery felt linear. 

 

Are you sure it is linear when you slam throttle?

:XD:

My friend who's driving a car with the same 208bhp engine mentiones that there's a lag when WOT from standstill, similar to Lexus.

 

I think thats what davidtch was referring to.

 

But yes, when driven normally the acceleration is linear

merc 2.0t only 208hp? I thot germans usually tune higher (not referring to likes of amg, rs) like 250+ in new q50.

Note I say official numbers

Because I recall that FXT's official spec is 7.9s (same as mine)

Could be a misprint for harrier. The rated power from borneo's brochure is 227. Here they put 231 (prob the PS figure).

BHP is not everything.

 

I have 241 bhp but I lost in a friendly sprint to my friend's 184 bhp Cooper S which is a bimmer engine.

 

I will also lose to the C250 in this aspect although it's "only" 208 bhp.

 

Weight, gearing, cd etc.. there are many factors other than bhp.

I don't dispute that other factors matter too for overall performance including weight of driver

That Q5 250HP engine is a gem, too bad the handling doesn't match the engine.

I don't dispute that other factors matter too for overall performance including weight of driver ð. I was just surprised at the relatively lower state of tune, unless merc uses the same 2.0t engine across diff series and has a diff tune for each.

Sorry I got u wrong in the first place :)

 

Maybe it's due to strict euro emissions that's why they tune it down?

 

But I think they use the same engine across multiple models with various states of tune.

Yours is a weighty car? Weight makes a big difference unless you have a 5-6l turbo. Then aircon on 2-4 passengers also cannot really feel the diff.

Merc 2.0T engine has 3 tunes

 

200 ~180hp

250 ~200hp

300 ~ 240hp

Yeah same with BMW. With the 500cc per cylinder design concept. I wonder who copied who.

That lag could be tranmission & prop shaft (either RWD or 4-matic).

 

FWD will be almost ZERO lag.

Current 500cc per cylinder design concept is used interchangeably between Petrol & Diesel.

The best practical test of different HP and Torque, drivetrain and weight, is the AMG DRAG BATTLE. Edited by Mkl22

My car is 430kg heavier than the Cooper S

Let me try and I let you know.  :D

 

But based on my theoretical concept of how turbo engine works, when WOT, the rpm might have overshot the 1, 200 to 4+k rpm drop off in otherwise very flat 350nm max torque, especially in 1st gear, it is how fast the gear change from 1 to 2 or even 3rd gear that determines how fast you drop back into your powerband (when gear shifts up, your rpm drops) for effective utilisation of your engine's power put to the ground. 

 

That's why for my conventional turbo cars, I never WOT to achieve max acceleration. Key is know where is your max torque RPM band, aim to reach it and keep within that band for best result. A fast and close ratio AT gear box helps.

 

GS450h, yes, I will WOT, why? Because gs hybrid is setup such that during WOT, the v6 engine will take it-s time to deliver it's NA linear power and electrical motors will give their max output from 1 rpm to augment the acceleration. The car don't even have a tachometer.

I thought the current Mini is using the Prince engine made by PSA not BMW - see link below. PSA also makes the engines for 316 and 318, like Nissan making engines for A-Class, B-Class and CLA.

Dunnoe of still true but it is popularly known that Japs/korean tend to declare engine output while germans tend to give on wheel figures. 

 

Used to own a legacy 2.5GT, paper specs is 250bhp, when going for tuning, the pretune on wheel figures are only about 205-210bhp.

 

Anyway specs are specs, what is important is real world drivability. A car tuned/setup for winning traffic light sprints will not be fun to drive in any other road condition like parking or jam.

I just check the sgCarMart, FXT is 7.5s, so officially still a tad slower than Harrier Turbo.

What's Harrier turbo's 0-100km time? Is it faster than FXT's 7.5s?
