What is better? Manual or automatic? How do they work? Which one to choose? Why? This site is dedicated to unbiased information / pros and cons about these two types of transmissions. Don't forget to add your own thoughts at the end of the page. If you are too lazy or don't have time to read all that's on this site here's the one sentence executive summary: manual transmission (MT)cars use less fuel and give you more control over the car but are less convenient, while automatic transmissions (AT) burn (a little) more gas, provide less control but they are easier to use. Costs Manual transmissions cost less than automatics to begin with. When you go to a car dealear you will notice that the stick-shift version of the same model is about a thousand bucks cheaper. Sometimes a thousand dollars seems like not not so much when it comes to buying a new car but forget about the car itself, think of what you can do with an extra $1000. In the long run, manuals require ...

While we may think we know a lot about cars, sometimes it’s nice to have a refresher course on what makes some things tick. In this case, we get to see illustrated for us exactly how a turbocharger works. Its fascinating to see all of the moving parts, and having a better understanding of this key process makes you, my friend, a better car guy.

 Fonctionnement  des boîtes de vitesse automatique? Beaucoup d'entre vous se posent la question: une boîte de vitesse automatique, comment ça fonctionne? Est ce que c'est facile à démonter, à réparer?  Souvenez vous du sketch de Fernaud Raynaud: '' Dis papa, comment ça fonctionne un sous-marin atomique? ''   Réponse désabusée du père: '' C'est étudié pour ! '' Et bien la boîte automatique, c'est un peu pareil, c'est étudié pour ! Mais nous allons essayer de vous expliquer un peu les grandes lignes. Tout d'abord un petit rappel sur le fonctionnement d'une boîte de vitesse mécanique (ou manuelle): - ce type de boîte est constituée généralement de 2 arbres: un arbre primaire et un arbre secondaire. Chacun des arbres porte des pignons - L'arbre primaire (ou d'entrée) est relié à l'arbre moteur via l'embrayage, porte les pignons primaires fixes. Il y a autant de pignons que de rapports de boîte.  L...

If you have ever driven a "moped", you've already dealt with the principle of continuous variation! The speed varies gradually, without gearshift. The most common system is composed of a metal belt and pulleys, the conical winding diameter varies automatically according to the engine speed. Some models are still a batch mode, allowing the driver to pass himself reports using a lever. For now, its high cost of production usually reserve this type of transmission in high-end models. advantages: driving comfort (fresh Conduct) operation totally devoid of jerks range of high variation (equivalent to a minimum of 6 classic reports) auto or sequential mode available cons: overconsumption nervous reactions (literally Braille engine during hard acceleration, and says braille says consumes ...) grip that can be disconcerting no performance driving Some examples: Nissan Xtronic, Autoronic Mercedes, Audi Multitronic ...

Although we found an auto mode and a sequential mode, as a single-clutch AMT, the ISR dual clutch design is very different. It is in fact an assembly of two half-gearboxes. Each has its own clutch. Thus, when a gear is engaged, the following report is pre-committed to him, which authorizes a change extremely fast speed (less than 10 milliseconds). Furthermore, the torque transmission is continuous, thereby avoiding any jerk. In short, dual-clutch AMT combines the advantages of the BVA and ISR single clutch, without their drawbacks. This type of transmission meeting today a success. advantages: driving comfort auto or sequential mode consumption gain passages ultrafast report cons: more expensive to buy than a BVA and a BVR if the passage between the two reports is fast, it is much less so when we want to downshift 2 gears at once and vice versa (uphill). Some examples: Peugeot DSC, EDC at Renault, Mercedes 7G-DCT, DSG / S-Tronic with Volkswagen and Audi ...
