New owner 488 GTB

May name is Horst, ( from Germany ) since end of February I am an owner of
488 GTB, last Ferrari was 430 Spider. Resumee of first 2000 km:

Critical remarks: 8000 rev/min I never see, I checked OBD 2 data, maximum
rev is 7850 rev/min but only in LC Mode, in manual rev limiter comes at 7500 U/min
and in automatic mode is maximum rev 7450 U/min. Dashboard revmeter is very
accurate, no visible difference to OBD 2 values.

Acceleration time 100-200 kph is 5.4 s measured with Permance Box, tank full, no
co - driver. 200-250 kph : 4.9 s. But only in LC Mode!
Due to lower max. rev in automatic or manual mode at 194 kph is gear switch
necessary from 5th to 6 th gear and about 0.3 you loose. 5.7 s instead 5.4 s with LC.
I guess 670 PS at 8000 U/min is a marketing gag!

Regards Horst

 

Furher critical issue is automatic mode at 488 GTB: car is switching as early as
possible in 7 th gear, even at cold engine and even in race mode.
Gearbox is not happy running in 7 th gear at 1000 rev/min at 45 kph, pushing slightly
accelerator at 45 kph in 7 th rattle noise due to torsion vibrations is audible, that is normal,
then you switch down manual in automatic mode to 6th or 5th gear, but after
5 s car switches again in 7th gear driving in town with 50 kph here in Germany.
At least in race mode lowest possible rev's in 6 th and 7 th gear should be increased
in automatic mode. ( see Porsche PDK , 7 th gear is blocked in S + mode )

Regards Horst

 

Thank you for these interesting insights and data points.

I measured following maximun gear speeds ( OBD 2 rev values):
at 7850 rev/min (is maximum at my car) :

1 th gear: 68 kph, 2 th: 101 kph, 3 th : 132 kph , 4 th 165 kph, 5 th: 203 kph,
6 th: 257 kph , 7 th : 350 kph ( theoretical)

The gap between 6 th and 7 th gear is little bit too big, driving on
German Autobahn acceleration 250-300 kph could be a lttle bit faster,
but 0-250 kph times about 13 s + is good, more is not possible with
about 670 PS.

I will make a dyno run on best German Maha dyno and will post it here,
I will drive drive further 2000 km , then running in of engine is definitely.

Regards Horst

 

Hi Horst

Thank you for the very accurate data.

It will be good to see the dyno results too when you get them.

Would be good to see some pictures of your car and your thoughts on the overall driving experience.

Regards

Michael

A minor critical remark is upper line left wing and upper door line, at drivers side
a offset, but this is due the window rubber, triangel in door window is mounted little bit
offset. Can be easily readjusted

right car side is alignment ok.

An last critical remark is a visible bar code label through the rear grid.
But very minor quality issues, but I posted pictures to customer support and
answered me to forward pictures to 488 product mananger...

In my next postings I report about my " positive " impressions after driving 2000 km
488 GTB !

Rev limiter at 7500rpm is surprising. I don't have my 488 GTB yet so I have no firsthand experience.

 

I can confirm this video: rev limiter 7500 rev/ min in manual mode and
7850 rev/min ( OBD 2 read out) in LC mode

https://m.youtube.com/watch?v=QZXEiviHXLs

 

Clear is a nearly 4 l V8 biturbo does not need 8000 rev/min for 661 hp, 488 has no
titanium rods, it has steel rods as typical for turbo engines.
German " Sportauto " measured on dyno 700 PS max. power at Supertest at 6700 rev/min,
so reving to 8000 rev/min would not make sense.
I guess Ferrari Marketing wanted to see 8000 rev/min in specs to ease " good by"
from natural aspirated V8 engine

 

Here Dyno Run from Sportauto magazine, max. 700 PS ( 690 hp) at 6700 revs/min, then decreasing

Congratulations on your new car.

Your left fender (wing) mismatch seems to be related to the installed position of the fender being too far outboard (too far up, in the picture as posted) at its aft end. How is the fender-to-door alignment on the body side - any step?

 

Interesting. I'm sure the 488 is fast. Just a bit surprised about the rev limiter. Thank you for sharing detail information.

 

This is the inherent issue with turbo engines, general low power peaks and I agree revving beyond that doesn't make much sense.

That being said the 488 is plenty fast!

 

ich stimme zu!

 

Here my 488 and my 997 turbo convertible. I ordered November 2015 and delivery
was end of February 2017, 15 months delivery time! Long time, promised from
dealer was 09/2016, but I fixed price at " delivery" , so I got 203 k basic price,
with Goldrake carbon seats Ferrari wing embleme and so on total price
217 k Euro including German VAT. Delivery to my home ( 100 km distance from dealer)
via truck was free.
The 997 turbo ist tuned to 580 hp and goes 6.7 s 100-200 kph like a 991 turbo S,
1 s slower than my 488 in LC mode is 488 GTB 1.3 s faster.

Good news on 488 GTB first 2000 km : oil consumption is not measurable so far, fuel
consumption about 16 l/ 100 km including German Autobahn longer distance over
250 kph and several GPS measurements like 100-250 kph, similiar to my
C63 AMG, depending on speed/acceleration, turbo engines only fuelsaving at low
engine load

That' s the 997 turbo convertible and 488 GTB

No problem deciding which one looks better and which one I would rather have. I had a 991tts in silver, very fast, tuned to 700whp, probably too much for the PDK. I traded for a 2017 Cali T HS new off the showroom floor, not nearly as fast but more fun and much better looking.

 

One very last critical issue on 488 is infotainment, cockpit is reduced with push buttons with
integrated arrow keys , but handling is not easy, for a daily driving car, I would prefer
push buttons to switch from radio to navigation or phone or so on..

Not a progress in my opinion, but tidy interior, this issue was critisized in several
488 tests and I can confirm. For me ok as 488 is for me fun car, not daily driver,
I need no infotainment.

Cockpit/ interior quality is good, new Audi R8 V10 bench mark, but not all knobs have to be made from solid aluminium..quality is ok at 488, also body quality gaps between doors and wings are are good.


But now the positive aspects of 488 GTB!

The sole of the car is still the engine. Best turbo engine on the market, state of art,
no doubt, I drove lot of Porsche turbos from 996 to 991 turbo S, AMG GT-S,
Mc Laren 650 S, throttle response is fantastic, no delay like McLaren or 991 turbo S.
Seemless power supply up from1500 revs/ min,
close to 458 engine, powerfull, but no turbo punch like tuned 911 Porsche turbos,
smooth power delivery from 2000- 7500 revs/min for good driveability on race course
or in Germany on my Black Forst roads. Due to extreme short gear ratios, 488 engine
is extremely lively and punchfull.
80-120 kph in 4.5 s ( without co- driver, tank full) I measured with Performance Box in
7 th gear is excellent, also 100-200 kph in 10.5 s in 7 th gear.
Sound of engine is good up to 6500 revs/ min, deeper than 430/458, no drowning,
but over 6500 revs/min no screamimg like 458, this is known.

LC is not as brutally as in a 991 turbo S , starting rev is 3000 revs/min.
3.0 s 0-100 kph is only possible on very grippy roads

 

This was my first LC at 8 degree Celsius outside temperature: 0-100 kph in 3.6 s, bad due
too much wheelspin, but 100-200 kph in 5.4 s is good, it was a flat road,
tank full, without co - driver, odometer: 1500 km. German Autobahn, no wind.

That is a very good 100-200 as the best I got in my 700whp 991tts was 5.77s. Other guys with more horsepower or using methanol injection were doing better but this is stock. The 488 is a very good balanced package of performance, style, sound and comfortable / high quality cabin. The 991tts cabin was good and I see that the 991.2 has some improvements in the PCM interface but it's still small. The new steering wheel has a lot of stuff on it that I am not really sure I want there but some do. Anyway, you have a nice car there Horst. Good data collection too and you are the first owner I have seen do that here. Go Vbox!

BtW, not sure if you are aware but if you save your data to the SD card, you can use vBox Verify and get a lot of results graphed with more detail than just a picture of the screen. For example:

991 turbo S has a disadvantage as 4 th gear goes up to 224 kph,
488 has the advantage, that 5. th gear goes to 203 kph at limit of
7850 revs/min in LC mode, the very short gear ratio helps 488 for good
100-200 kph times.

I was for a long time member of German Porsche pff forum,
we talked al lot about GPS measurement and Racelogic Vbox 3 i, 100 Hz
and so on.., clear, you can cheat acceleration times,
Qstarz GPS you can not take for 0-100 kph measurement as
this GPS boxes measures with 1 - foot rollout, SD card is necessary for
proof of acceleration times, that is clear, but my first checks
with Performance Box on German Autobahn A5 confirm
engine power, in Porsche Forum I made power calculation
of GPS acceleration data. I guess 670-675 hp or 680- 685 PS has my 488 GTB,
with 100 Hz GPS box it is possible to calculate horse power on nearly +/- 5 hp.

Dyno result 700 PS in Sportauto may be too high, but I plan to make
best measurement on a Maha MSR 1050 dyno, state of the art, best dyno
today!

In Germany we do not accept wheel power, because wheel power depends
on roll diameter and inertia of the rolls and is therefore different from dyno to dyno.

My measured 5.4 s 100-200 kph is not surprising, in Italian Quattroruote magazinze
488 GTB went in 5.2 s 100-200, same car in German Autozeitung Supertest 5.4 s and same car
in German Sportauto Supertest in 5.6 s 100-200 kph, but Sportauto measures with co- driver!

680 PS - 690 PS is typical for 488 GTB, I do not know any modern turbo engine failing qouted power!
991 turbo/S have small surplus of qouted power of 2-3 % and 488 also. Mc Laren test of 720 S showed
720 PS, but not much more

 

Good to know. I know the shift speeds on the Porsche in mph as I have plotted speed vs rpm many times but I had not looked at it on the 488. You can see that long 4th gear on the Porsche goes to 140mph or 224kph. BTW, this was done on a county road with new PZero N1 tires.

Fast Porsche, the Techart 991.1 TTS with piggyback box and 620 PS ( dyno was 640 PS engine power)
goes 100-200 in 6.0 s without co-driver.

Fastest 488 GTB measured with GPS I know is tuned Novitec 488 GTB,
this car goes 100-200 kph in 4.1 s but has nearly 900 PS engine power.
