Study: car evolution trends

Car classification in Europe is not officially regulated, instead, it is defined in relative size with other cars.

Today the average lifetime of a car model is 6 years for compact and medium cars and 8 years for mini and luxury cars. Is normal for cars to grow over years, as technology advance and more gadgets should be included under body, but in Europe since 1990s, the cars are growing crazy with about 10-20 cm per model change, which is exaggerate, based on technology evolution, 5 mm per year is enough. This non-natural grow causes companies to abandon large models and introduce new smaller models below existing models.

Some brands do not follow the common class sizes, making cars with intermediate sizes, these are usually considered being part of the smaller class, causing further increase in size of car classes.

Seems that all European companies wants to make a car bigger than competitor’s cars of same class. This leads to 2 cm / year increase in average car length in each class. The cars get fatter also in width, this is an issue for parking design, since in most countries the parking lots are 2.5 m width, most compact cars were under 1.7 m width in 1998 but since 2008 most are over 1.8 m.

How many distinct car models are being produced in the world?

The answer of above question depends by how do you define “one model”.

Should we count BMW 3-Series as one model? Should we count each body type (compact, saloon, touring, coupe, cabrio)? Should we count each engine version (318i, 320i, 325i, 330i, 335i, 316d, 318d, 320d, 325d, 330d, 335d, M3, in case of 3-Series E90)? Should BMW M3 or BMW 3-Series Gran Turismo be counted as submodels of 3-Series or as separate models?

Car Length Evolution

PDF chart with 640 most common car models from Europe since WW2 to present. Took 10 hours to write each car model at correct position in the chart, based by year of launch and length in millimeters, using AutoCAD then exported as PDF, useful for garage builders and students or hobbyists researching the car evolution.

Carmakers produce too many models?

The number of models produced by each car manufacturer increased over years, modular platforms allow car markers to produce a large number of models with little cost, creating new niches to cater different types of buyers. But is this really necessary? How long this trend can continue until they realize that have too many models?

If you make a saloon on a platform, and a wagon on a platform, why not make a crossover? Why not make a slightly sportier version of that crossover? Why not make a really sporty version of that crossover? Why not make a coupé version of that crossover? Why not make a slightly sporty version of that coupé version of that crossover based on the saloon? Why not make a really sporty version of the slightly sporty version of that coupé version of that crossover based on the saloon?

Biggest cars

If you are an architect and designing parking garages you may ask how big are the biggest cars. Biggest mass-produced cars are today in 5.1-5.3 meters range, such as Audi A8, BMW 7-Series, Jaguar XJ, Lexus LS, Mercedes S-Class. However, there are few even bigger cars produced in low numbers, some over 6 meters long, they are listed in this article.

Used cars database

If you want a complete and accurate database of cars sold in your country, used cars classifieds websites are NOT a good place to source data from, because they are variable data, every day new cars are posted for sale while others become inactive, many car models are duplicated and some car models are missing because none is on sale today.

But there are several cases in which you need specifically to extract data from used cars listings, example:

  • You are doing an analysis of most popular car models, their average price, age, mileage, etc.
  • You are training an image recognition software, thus need thousands of amateur images labelled with car make and model. Used car classifieds websites are best option to get such images.
  • You want to start your own used cars website and can do this by copying listings from an existing website, with a link to original website so people can contact seller.

Car classification

Car classification in Europe is not officially regulated, instead, it is defined in relative size with other cars. Since 1990s, the cars in Europe are growing in length with about 10-20 cm per model change. Seems that all European companies wants to make a car bigger than competitor’s cars of same class, increasing car class standards with about 2 cm per year, which is exaggerate, based on technology evolution, 5 mm per year is enough.

List of car database updates (change log)

Teoalida’s Car Database is the MOST UPDATED database ever existed. Rarely is passing a week without adding +1 model or changing something in one of databases. Here I summarize updates by month.

(only major updates are listed here, which takes more than 1 day and are done every few months. India car database is updated on 1st day of every month so is not listed here).

America vs Europe vs rest of world

If you are a business working globally rather than in a specific country, or working in some other country than the countries covered by my standard car databases, you may be looking for a global car database.

But… this is not really possible. Car specifications vary depending by country of sale for models having same name, and for accuracy reasons, a car database should be specific to cars SOLD in one country, or with some compromise of quality, to one continent.

Pricing

I offer various packages such as no specs / basic specs / 2000-present / new cars only at cheaper price for people who do not need old cars or too many specs.

Car photo database

In 2015 I started using web scraping software to quickly create databases extracting data from various websites. Scraping software do not extract only text (model names and specifications) but also Image URLs (link to image corresponding to each car model, usually in same resolution).

Do you provide PHP scripts?

Because of large number of databases that I am selling, and because each customer have different requirements in integrating my database in his website, there is not possible to make ONE plugin and give it to every customer purchasing a database.

Several free plugins for WordPress do exist (example WooCommerce YMM search) but it can be used only for online stores made with WooCommerce and the only car database that works with it is the Year-Make-Model.

Interoperability with other products

As an independent data provider, I do not guarantee interoperability of my databases with other products available online. Actually there is no interoperability between my own car databases, each one being developed independently from different source.

Most common conflicts are at BMW and Mercedes, some show model “BMW 3-Series saloon” with trim/variant “320i”, others shows model “320i” with trim/variant “saloon, touring, coupe, cabrio”, etc, others shows model simply “3-Series” with trim/variant “320i saloon”, and some of those who show 3-Series as model put M3 as separate model instead of a trim/variant under 3-Series.

How often do you update databases?

Dedicating most of my life on data providing industry, I managed to provide the most updated databases ever sold on internet. Proof: List of updates.

The greatest thing is that in case of databases made using an automated scraping script that takes less than 24 hours to run, you can request anytime to have database updated today free of charge. Once a customer request update and it is done, all existing customers will be notified to download latest update.

How do I receive updates?

I use Easy Digital Downloads plugin for WordPress to generate database download links after payment, I set the links to expire in 1 year, and you can click your link again as many times you want to download latest version of database.

Moreover, after every update of each database, I click “resend receipt” in WordPress dashboard to each customer, and you receive a new email that reminds you that a new update is released.

Do you provide other formats beside Excel? (CSV, SQL, XML, JSON)

Anyone can convert XLS to SQL: open .XLS file, do the necessary changes in Excel > save as > choose CSV format > go in your website cPanel > phpMyAdmin > create a MySQL database > import CSV file.

Starting from 2015 I provide CSV and SQL by default for small databases (Car Models List, Car Nameplates List, Year-Make-Model) at no extra charges (pay once and receive 3 file formats). I can provide for bigger databases at request.

Do you offer refunds?

If you buy a physical product from a real store, you can return it to store undamaged and get refund. But in case of digital car databases, returning is not possible. Since starting selling in 2012, as 2017 I done over 1000 sales and had only 3 or 4 cases of people asking for refunds. If any customer report problems I always choose to fix the problem rather than refunding, until every customer is satisfied.

What is the source of data?

The original databases I made for Europe (Car Models Encyclopedia, Car Models Database, Car Models & Engines Database) were made by entering data manually from AutoKatalog, a yearly publication made by Auto Motor und Sport, the leading German car magazine and one of the most reputable car magazines in the world. AutoKatalog is published yearly since 1957 in about 15-20 European countries.
