I) PerfectPower Database

(187 cars as of Fri 08032024)

PerfectPower created its own database on December 11, 2023, to which you will have to refer to enter the 8 basic data of your Car sheet necessary for power measurements:

- Car weight

- Engine displacement

- Number of cylinders

- Transmission

- Tyres dimension

- Gear ratios

- Final ratio

- Cd.A

This database is accessible via an Excel file which is constantly evolving and available on Google Drive at the link below:

PerfectPower Database

However, you have to know that there are hundreds of thousands of car models in the world, and a whole life would not be enough to create a complete database (the calculation is easy to do...), so it will limit to the most popular sports cars and those of PerfectPower users (see note 4 below), thanks for everyone's understanding!

Note 1: The PerfectPower database is structured as follows:

- Each car is identified very precisely by its full name (make + model), its power (with its standard), its type of gearbox (M = Manual or A = Automatic followed by the number of gears), and its years of production (1st year - last year). Plus a fifth optional information: its sales market (EUR = Europe, N-A = North America, FRA = France, USA = ... USA, JAP = Japan, AUS = Australia for the most common) when the car is not sold worldwide or when it has different characteristics depending on the region of the globe.

- Each car not only has the 8 basic data (in red) to enter in PerfectPower, but also indicative additional data (in blue) whose number may increase over time.

- Two car weights are given: The claimed (manufacturer) weight (marked C, and in blue) given as an indication, and the real weight (marked R, and in red) corresponding to a weighing carried out on a precision scale (typically +- 0.1%) by an independent source (PerfectPower, automobile magazine, technical control center), or to the manufacturer's weight when none of these three sources is available or the manufacturer's weight is considered sufficiently reliable (American cars). In all cases, it is always the real weight (the one in red) that you must enter in PerfectPower!

- For the sake of transparency, the source used for the real weight is systematically given in the Notes column (last column), here is the nomenclature:

PP = PerfectPower (Intercomp SW500 scale (NIST certification +- 0.1%))

WC = WeightCars (French website listing the real weights of sports cars weighed by French automobile magazines on the UTAC scale (French private organization of tests and homologation))

AM = Automobile magazine (with weighing of cars on a precision scale like that of the UTAC)

TC = Technical control center

C = Claimed (manufacturer)

When several values are available, it is always the lowest which is used as a reference for the sake of homogeneity (car with the minimum number of options).

- And finally and always for the sake of transparency, the sources used to populate the PerfectPower database itself are given to you below:

First of all, myself, the creator of PerfectPower and its website, who have known the automobile world since my childhood and have in mind thousands of reliable values on all kinds of automobiles and also own many automobile magazines (French and American)

The most comprehensive automotive database in the world to date, revealed below in note 2

The five sources given in the previous point to obtain the real weights

And finally various other Internet sources (generally English-speaking) specialized in the 2 types of "difficult to access" data (gear and final ratios, aerodynamic data) when I was unable to obtain them through one of the first two ways

Note 2: If your car is not in the PerfectPower database, refer to the most comprehensive automotive database in the world to date, both by the number of cars it contains (hundreds of thousands!), and by the number of technical data for each car:

The Automobile-Catalog

However, this database is not yet completely finished, its designer and his team proceed alphabetically and are currently working on letter S (Seat, Suzuki, etc.), and therefore a certain number of models are missing in the brands starting from letter S (S, T, etc).

Note 3: All cars in the PerfectPower database have a direct link in the Automobile-Catalog (when they are also present there) available in chapter II below.

Note 4 to PerfectPower users only: If your car is neither in the PerfectPower database nor in that of the Automobile-Catalog, you can contact me by mail from the application (Email contact button located at the very bottom of the Setup screen) by giving me the make, model, and year of your car, and this one will be added to the PerfectPower database within 24 hours following your request.

Note 5: The data from these two databases being those of strictly original cars, you may need to customize them if your car is not completely original (car weight, tyres dimension, etc). Moreover, here are important notes regarding some of these data:

- The car weights given in the PerfectPower database (real weight and claimed weight) and in the Automobile-Catalog (claimed weight) are systematically weights corresponding to the DIN standard (the most logical and "intuitive" of all... ), namely car with all fluids and in particular the full tank of fuel but without occupants or luggages.

- The problem with the weight claimed by the manufacturer (and this regardless of the standard used...), is that it is sometimes optimistic (and this in a very variable way according to the manufacturers / models...), and this is precisely why the PerfectPower database adds the real weight, and it is one of the only ones in the world to do so, and with unprecedented transparency too! However, months of analysis since my move to the USA in November 2021 have allowed me to realize that this cheating phenomenon is especially true in Europe (in particular in... Germany, that's the height!), but not in the USA where the manufacturer's weights seem to correspond well to the real weights: I therefore guess that here (in the USA), the standards and/or controls are much stricter, and I welcome this because completing the PerfectPower database becomes much easier with American cars where I just have to copy and paste the manufacturer's weight to get the real weight!

- The car weights being given with a full tank, remember to take into account the level of fuel present in the car at the time of the measurements! An example: your car is weighed or announced at 1300 kg with the full tank, but you only have half a tank of 60 L ==> you will have to enter 1300 - [(60-30) * 0.75] = 1277.5 kg or 1277 kg rounded (note: calculation with conventional gasoline of average density 0.75).

- The tyres dimension to enter is always that of the drive wheels, and for a four-wheel drive it is always that of the rear tyres (and whether the fit is symmetrical or asymmetrical).

- The number of gear ratios has been deliberately limited to 7 in the application, which covers well over 99% of the cars in circulation on the planet, thank you for your understanding! In any case, the power measurements only having to be performed in 2nd or 3rd gear with a serial car, the setting of all the other gears is only used for the performances simulator, and not setting gears 8 and + on a gearbox with more than 7 gears will make absolutely no difference on the results provided by the simulator, with the only possible exception of the max speed.

- It is possible with PerfectPower not to have to configure the gearbox and final ratios by carrying out a procedure identical in all respects to that systematically used on chassis dynamometers: the rev calibration (guide, chapter IV-6).

- It is also possible with PerfectPower not to have to configure the Cd.A by choosing to use the losses calculation mode by measure in coastdown for power measurements (guide, chapter I-1-C). However, this procedure is not recommended because of the relative difficulty of implementation on open road, not to mention that it is not possible in any case with an automatic gearbox.

Note: The transition in 1990 from the DIN standard to the ECE standard to express engine powers in Europe (2 to 2.5% less power to schematize) generates small differences here for certain Peugeot from the 80s-90s between the powers of the PerfectPower database (which chooses to remain in the DIN standard so as not to create confusion!) and those of the Automobile-Catalog (which chooses to scrupulously respect the change in standard in 1990 with the disadvantage of making "believe" in a slight drop in power of a model during its life when it is not the case!)! Typical example with the 205 GTI:

205 GTI 1.6 115: 115 PS / 113 hp DIN from 1985 to 1990 - 113 PS / 111 hp ECE from 1990 to 1992

205 GTI 1.9: 130 PS / 128 hp DIN from 1986 to 1990 - 126 PS / 125 hp ECE from 1990 to 1992
