Producing an automobile mostly comes down to physics and engineering, but, like chrome, paint mostly comes down to chemistry. During the rapid development of the motorcar in the late 19th and early 20th centuries, the complex chemical compounds and sophisticated techniques employed by today’s carmakers simply didn’t exist. Some early cars were hand-painted. Like, with a brush. Even as automotive production grew, paint with a varnish-like composition was the most common finish, applied in...

Long before SRT, R/T was top dog of Dodge performance. If your Mopar had that two-letter badge in the grille, it was enough to send even the baddest of would-be street racers packing. These cars would go toe-to-toe with SS and GT cars all day long, often besting them from stop light to stop light and on the drag strip. What does R/T actually mean, though? What equipment did it entail a car came with? R/T is an acronym that stands for Road and Track. When it first appeared in the late 1960s,...

Internal combustion engines are commonly referred to by their displacements, whether its old-school cubic inches or more modern CC and liters. An engine's displacement is calculated using the diameter of its cylinders and the length of its crankshaft stroke to determine the volume of each cylinder. That volume is multiplied by the number of cylinders to get the total displacement. There are two ways to increase the displacement of the engine in your car. You could bore the cylinders to a...

This YouTube video explains exhaust backpressure, exhaust scavenging and turbo pressures.

The following Motor Trend article, describes in detail, how the MDS system works. What Is Hemi MDS? (motortrend.com)

HERE'S WHAT HAPPENS WHEN YOU PULL #2 FUSE (older Challengers) Pulling Fuse F2 resets: All PCM DTCs erased. All OBD2 monitor results erased. All "long term fuel trim adaptive" values reset to Zero. Long term Fuel Adaptive trim will now start over the next 100 engine start cycles. Cycle the headlights as described above will create a Short Term Fuel Adaptive trim table over the next 50 start cycles. Driver Adaptive? Driver Adaptive and related fuel table trim is probably the least...

Electric cars need to be recharged frequently for efficiency. However, charging an electric car is a much different experience than refueling a gas or diesel vehicle. Instead of a few minutes, charging an EV can take anywhere from 30 minutes to over 30 hours. This is because there are actually three levels of electric car charging. Levels of Charging NeoCharge provides a breakdown of the three levels of EV charging. Each level of charging is defined by the amount of voltage, which...

Well I've been waiting around to win the lottery so I could afford some LED tail lights. So just for giggles I bid 400 bucks for a set on eBay and the offer was accepted. I ordered my three layer center decal in advance so I put it on before the lights. It was a little tall so I just trimmed it before I took off the paper. I always wanted a blacked out rear end but I never liked those covers that went over the stock lights of the 2008 through 2014. I purchased the smoke set and it does not...

What is Blind-Spot Monitoring? Blind-spot monitoring one of those features we didn’t know we needed or wanted until carmakers began offering it. Volvo was the first, incidentally. It offered its Blind Spot Information System (BLIS) for the S80 in 2005. BSM is just what its name implies. It keeps an eye on the space just off the rear quarter areas of your vehicle. These blind spots can hide a vehicle approaching in an adjacent lane because many drivers improperly set their car’s outboard...

We are now entering the electric car age. These vehicles are powered by Li-Ion batteries. This type of battery is energy dense and durable. However, it can also be unstable and prone to catching fire under certain circumstances. But not all Li-Ion batteries are suited for vehicles. How Do They Work? Lithium ions store the energy by creating an electric potential difference between the negative and positive poles of the battery. Those are isolated using a separator material to prevent...

Hello, I have a 2014 Anniversary Edition Challenger. purchased it new in 2014. Since then, I have NOT seen any other anniversary models on the road, except I did see a 2014 anniversary Charger. Everywhere I go, a lot of Mopar guys ask me, What model is your car. In the winter time, its kept in the garage, covered and I drive my Ram. Which is also awesome. Several people at car shows ask if I want to sell it. The answer is, always, NO. I love this car. I have under 30,000 miles. Now, I've...

When most people think of wind tunnels, an aerospace tunnel usually comes to mind. This helps designers and engineers understand how aircraft will behave during various flight conditions. Automotive wind tunnels are usually very similar to aerospace tunnels, but they often feature a rolling floor that lets test engineers simulate a car driving on the road at various speeds. What are Wind Tunnels? Wind tunnels are large tubes with air blowing through them which are used to replicate the...
