Hennessey's 1,000-horsepower Camaro Exorcist is ready for the Demon

  Hennessey's 1,000-horsepower Camaro Exorcist is ready for the Demon Watch it destroy some tires at the dragstrip.We've got roughly another week before Dodge reveals its hellish Challenger Demon, but Hennessey has already produced a rival. It's called the Exorcist, and both the name and Hennessey's press release make it clear the car is designed to be the anti-Demon. That may not come across visually, since on the surface it's just a standard Camaro ZL1 with decals. But underneath is an LT4 V8 tuned to 1,000 horsepower and 966 lb-ft of torque.

But what is horsepower ? How do we measure it? And most importantly, why does it matter ? To get technical, horsepower is 33,000 ft·lbf/min (supposedly, the amount of work one actual horse can do in one minute).

Horsepower is a standard measurement, whether you’re talking about a car or a shop vac, and the term is so commonplace that it’s easy to forget it has pre-vehicular origins. The term was coined by engineer James Watt (also namesake of the unit “watts”). As the story goes, while working with ponies in a coal mine, he estimated that an average horse could do 33,000 foot-pounds of work per minute. Watt lived from 1736 to 1819, so his work in horsepower predates the automobile’s beginnings in the late 1800s, though the same formula has been applied to measure the work potential of car engines and all kinds of machinery.

How Horsepower Relates to Engines

Watt’s horsepower formula is confusing, but there’s no need to understand it in order to understand why horsepower ratings affect cars. The reason car engines are measured in horsepower is because engines were invented, in part, to do the work that horses used to do, not because we need to know how much coal a car can move over a certain period of time. Horsepower is useful because it’s a consistent unit of measure, but a horsepower rating doesn’t tell us everything we need to know about an engine or a car’s performance. It just gives us an idea how that car’s power compares to the power of other cars.

Jaguar teases XF wagon ahead of its official debut

  Jaguar teases XF wagon ahead of its official debut Jaguar's XF Sportbrake is headed to North America this summerThanks to a birds-eye-view teaser, Jaguar confirmed an XF wagon is indeed in the works, set to debut this summer. It’s also coming to North America, aimed at the likes of the Mercedes-Benz E-Class wagon and the Volvo V90.

How do you explain brake horsepower ? Let’s start with explaining power . Simplified, the higher the bhp, the more power output the engine generates. Diesel engines develop more torque than the equivalent size of petrol engine, which is why they’re often prized in vehicles like goods lorries, vans

We live in a time of rampant horsepower overkill. Why does the family sedan need 300hp? We already have way more than enough power to get around town, why do we need to quadruple that? Don't get me wrong, I love going fast more than I probably should.

Horsepower vs. Other Factors

Generally speaking, the more horsepower a car produces, the better its acceleration, which is a strong factor in its overall performance. That’s why car marketing talks a lot about the horsepower ratings of high-performance or best-in-class models. However, there are always other factors at work. If you drive a compact sedan and a large sedan with the same horsepower rating, the compact will be quicker because it is lighter. Torque is another engine spec the affects a car’s performance. It measures twisting force. The more torque a car has, the better it can accelerate from a stop and the more strength it has for towing. The engines in high-performance cars are tuned so that the horsepower and torque ratings complement each other and provide a well-balanced driving experience.

The Advantages of Lower Horsepower 

High-horsepower cars get a lot of attention. They’re stylish and expensive, fun to look at, fun to ride in, and fun to drive. Auto manufacturers are always trying to improve their horsepower ratings for a competitive advantage in the market. In light of constant conversation over the newest and highest-horsepower cars, it’s important to remember that cars with lower horsepower are worthy of consideration, too. Compact, small, and midsize vehicles don’t need a lot of horsepower; in fact, they’re usually better off without it. Modest horsepower ratings help keep these popular vehicles affordable, fuel efficient, and safe.

The Trans Am is back!

Florida firm is building modern-day Trans Ams – “screaming chicken” graphics and allArguably, the most famous Firebird of them all was the 1977 Trans Am that starred with Burt Reynolds in the movie Smokey and the Bandit. But the one most coveted by true aficionados of the brand was the 1973-75 Trans Am Super Duty SD 455 – powered by a monstrous 455 cubic-inch (7.4-litre) V-8 engine.

But what is horsepower and why is it considered so important? Here are San Bernardino Mitsubishi's answers. In the days before cars, horses obviously carried out most transport duties, such as hauling carts and the like.

So, why does any of this matter anyways? For starters, understand the truth behind horsepower and torque will give you a better understanding of engines and why certain types of engines are good for some things and not others.

Lower-horsepower cars can even offer distinct performance advantages over their more-powerful competitors. A favorite example is the 155-horsepower Mazda MX-5 Miata. This affordable rear-wheel drive roadster has a modest engine for a sports car, but the reason it’s fun to drive is because it’s light and agile – it’s not concerned with achieving the highest speed in a straight line. The Miata is a pretty simple car, and if its engine made much more horsepower, the dynamics would change considerably, and not necessarily for the better.

Horsepower and Acceleration 

To further illustrate the effects of horsepower on performance, let’s take a look at the Porsche 911 lineup. This luxury sports car comes in a bunch of different trim levels and is currently offered with several different engines, although certain trim levels are tuned so that the same engine has different horsepower ratings. The quoted zero to 60 mph times are straight from Porsche’s website (and to keep things simple and consistent, we’ll use the numbers as achieved with a manual transmission where possible).

It certainly packs more visual muscle, but the end result is mostly all show and little extra go – the R/T’s 360-horsepower V8 remains unchanged under the hood, but the hood scoop and wider bumper openings result in improved cooling.

The base engine is a twin-turbocharged 3.0-liter six-cylinder. It comes in the Carrera and Targa 4, where it makes 370 horsepower and accelerates from zero to 60 mph in 4.4 and 4.5 seconds, respectively.

In the Carrera S (4.1 seconds) and Targa 4S (4.2 seconds), this engine makes 420 horsepower. It also comes in the GTS (3.9 seconds), which makes 450 horsepower.

The midrange engine is the 4.0-liter six-cylinder that comes in the GT3 RS (3.2 seconds) and the R (3.7 seconds), both of which are rated at 500 horsepower.

The top-of-the-line engine is a twin-turbocharged 3.8-liter six-cylinder. It comes in the Turbo (2.9 seconds) and Turbo S (2.8 seconds) and makes 540 and 580 horsepower, respectively. (These models aren’t available with a manual transmission; quoted times are with an automated manual gearbox.)

Consider More Than Just Horsepower

The Porsche 911 model lineup shows clearly that as horsepower increases, cars accelerate faster and zero to 60 times go down. We’re talking fractions of a second, of course, and zero to 60 times don’t matter much in day-to-day driving, but there are few better, more objective ways to compare the performance of similar cars. While the entry-level Porsche 911 would probably be powerful enough to satisfy most buyers, there’s no doubt that the more-powerful and more-expensive models offer better performance.

While horsepower is important, it’s not the only factor to consider when buying a car. Shoppers should try out different engine types (for example, a turbocharged engine and a naturally aspirated engine have different driving dynamics, even if the horsepower ratings are similar), and buyers who value performance should remember that a well-rounded vehicle has good steering and handling to complement its acceleration.
