1,000 Bhp Exotic Cars – Three To Choose From
If you love sheer power, and you want a car that produces 1,000 bhp, you now have three to choose from – and that is without going to the tuners like Ruf ofr Callaway, who will get this much power from engines that are currently in the 500- 700 bhp range. The tjree in the 1000 bhp club are the Bugatti Veyron 16.4, the Bristol Fighter T, and the Koenigsegg CCXR. Theoretically, these are all good for 250 mph in theory, but not in practice.
First on the scene was the Bugatti Veyron 16.4, the world’s fastest and most powerful exotic car, with a top speed of 248 mph.
Engineering masterpiece
The Bugatti Veyron 16.4 is quite an engineering masterpiece, with a W-16 8.0 liter cylinder engine mid-mounted driving through a seven-speed semi-automatic gearbox to all four wheels – four-wheel drive is definitely a good idea with this amount of power. Not only is it immensely fast, but with four-wheel drives it is very stable. It has ceramic brake discs and an air brake to help you slow down from over 125 mph.
A very surprising addition to the 1,000 bhp plus club is the Bristol Fighter T, which has an engine developing 1,012 bhp, just 11 more than the Bugatti! This is a front-engine, rear-drive car designed for high-speed touring.
To be precise, the V-10 engine in the Fighter T whacks out 1,012 bhp at 5,600 rpm. Bristol says that the top speed of the car is around 270 mph, but it has a limiter at 225 mph, which is just 4,.500 rpm in top! Not many will be made, making this a really exotic car.
Acceleration is not as good as you might expect – or maybe it is just modesty at Bristol Cars – at ‘under 3.5 seconds’ whereas the Bugatti Veyron is well under 3 seconds. The difference is largely academic – like the top speeds – but a mid-engined four-wheel drive car will accelerate more quickly than a front-engined rear-drive car. The Bristol Fighter just doesn’t have enough weight on the rear wheels to get under 3 seconds.
Twin turbo V-10
How did they get this huge amount of power? Well, like the other Bristol Fighters, the T has a tuned Chrysler V-10 engine of 8 liters. For the Fighter T they have added a pair of water-cooled turbochargers to almost double power so they could exceed that magic 1,000 bhp figure, getting 1,012 bhp at 5,600 rpm, with 1,036 lb ft (1,400 Nm) of torque at 4,500 rpm. That is quite a high speed for maximum torque, but the engine still produces a massive 800 lb ft (1,080 Nm) of torque from 3,000 rpm, upward.
The Bristol Fighter S has a top speed of over 200 mph, partly owing to good aerodynamics, but The Fighter T is an absolute stormer with a power-to-weight ratio of about 600 bhp per ton and a top speed of well, you name it!
Koenigsegg CCXR runs on ethanol
Now, along comes Koenigsegg with the Koenigsegg CCXR, based on the CCX supercar, but now this version is able to run on ethanol biofuel – E85. Because ethanol has an octane rating of over 100 RON – like racing fuel in the 30s – it gives more power than gasoline, as Saab has demonstrated.
In the Koenigsegg CCXR, power is up from 806 bhp – more than enough for almost everyone – to 1,018 bhp! Peak torque is an incredible 780 lb ft (1,060 Nm) at 6,100 rpm. That’s 25% more power.
With ethanol, power increases of 15-25% can be obtained for any engine so long as it is optimised with high compression ratio and other changes. In other words, don’t just pull up at a gas station, put ethanol in your tank and get 20% more power. It doesn’t work unless the engine is designed to run on it.
But that is not so difficult to do, and with George Bush trying to get more ethanol used in the USA, expect more to follow this route. After all, almost everyone loves power, even if they drive a car that is not very fast.

Buying an RV – Take some Advice
I fancy buying an RV darling. Ok Honey, go out and get one and we can spend all our vacation time in it and have great fun. Wrong, very wrong. Do not buy an RV if this is how you are thinking. Your RV will just be a waste of money.
Buying an RV is an important decision and something the whole family needs to be involved in. An RV is also an investment, an investment in time and cost but you will not see a profit on an RV, well not in financial terms but it can have a huge payback in terms of satisfaction and enjoyment but if you just rush out and buy an RV without giving it a lot of thought then it could be, at best, an expensive waste of money, and an RV can be, at worst, a marriage breaker. I know as I have seen it happen.
When we were trading up to a larger and newer RV, my sister in law from Atlanta decided she was going to buy our old RV. The trouble was it was her idea and not a joint family decision. She had been on vacation with us a few times and liked the lifestyle, thought it would be great for her daughter to spend more time in the countryside but she never really considered if her husband wanted an RV. He was the type who would choose a sports car to drive without thinking of where his daughter was going to sit. He liked speed, acceleration and easy maneuvering, not something you tend to find with an RV. It lasted a few years with him being unhappy with all his vacations in the RV, he bumped into a few trucks and did some damage to the RV, (which I had to repair), and was just generally unhappy with the whole idea of having a vacation in an RV. It got to the stage of seriously damaging their marriage. What went wrong? Well my sister-in-law did not sit down and really think about an RVer’s lifestyle.
Think about it, RVs can be small, they can be cramped compared to your house, RVs can be hard to drive and you can end up spending all your vacation just driving around. What she should have done is to rent an RV first to try things out. This way she could easily have seen if owning an RV was going to work.
So what do you look for when renting an RV.? Well I would think the most important is where it is at. Pick the area you would like to vacation in and they look for somewhere to rent one from. Think about how you are going to get there. Driving allows you to take more things with you than flying, so if you are flying then you may need to make sure that you rent an RV which comes fully equipped as some do not have things such as kitchen utensils in them or towels and so on, although many companies will supply these but sometimes they come at a price.
What about the size of your RV from small to large. I suppose this depends on what you want to achieve. If you are a family then you need a larger RV and so on. Just make sure that everything you need is available but remember this may mean extra rental cost. Do you want to tow a car behind your RV.? Some companies will let you, some will not and if you are in a hire car, does the hire company allow it to be towed behind an RV. Is the RV you want to rent capable of towing a large car or only a small car? These questions could go on but the best people to answer them are the RV rental company you are dealing with. They are the RV experts so ask them.
I could go on with information like this but it is just commonsense. Think about where you are going to vacation in your RV, think about how to get there, think about your RV in terms of size, think about the equipment you need for your RV, think about pets in the RV if you have a pet and think about who to rent your RV from. Get several quotes from RV rental companies and then compare them and read the fine detail to see what you get for the price and what extra you need to spend.
Once you have done all this pick a suitable RV to rent and a suitable company to rent your RV from and then just do it. Once you have tried renting an RV you will then have a much better idea if being an RV owner is for you and can then make the commitment to buy an RV Good luck and just enjoy it. I do.
A Guide to Motor Scooters
Motor scooters are vehicles with small wheels and a low-powered gasoline engine geared to the rear wheel. The first patents for “foot powered” scooters date back to 1921. Up to that time there were no motors attached to the scooter. They were propelled by “foot power.”
The old-fashioned foot-powered push scooter was updated to a Razor motor scooter under the direction of Gino Tsai, whose father was a mechanical engineer for the J. D. Corporation in Shanghai, Taiwan. His motor scooter took about 5 years to design.
Gino Tsai claims that the reason he invented the Razor motor scooter was due to the fact that his father had to walk for miles every day around the huge bicycle factory that he worked for because of his short legs. To solve this problem he updated the old-fashioned push scooter into what we now know as the modern Razor motor scooter.
When Gino finished the development of his motor scooter he began to market it to the public. It quickly became a huge success with customers waiting as long as six months for their orders.
Why was the Razor motor scooter so popular? The Razor scooter was made from lightweight airplane grade aluminum which can support over 1000 pounds without bending. It is foldable, which means it can be stored in very small places. It has small polyurethane wheels and a low-powered engine. Braking is activated by stepping down on the rear fender.
Today there are many different brands and models of motor scooters. We have electric scooters and gas powered motor scooters. They are very versatile and functional, serving many different purposes. They are patterned after motorcycles, but have smaller wheels, lower-powered engines and can be “stepped through,” unlike the motorcycle.
The most commonly seen style of scooter is the “folding,” or “foldable,” scooter. These are two-wheeled models that are typically used for traveling short distances around the neighborhood. Braking occurs when the back fender is stepped on, putting pressure on the back wheel and stopping its movement. This type of motor scooter is made for kids or adults and can also be used to perform tricks on. It is very compact in size and can be folded for storage in small places.
A unique feature of freestyle folding motor scooters is the “kicktail,” a portion of the foot deck that extends over the back wheel. This is what provides the leverage for performing tricks. Motor scooters with “kicktails” are called freestyle scooters and usually have hand brakes due to the fact that the back fender allows for the performance of tricks instead of braking.
Electric scooters are generally bigger and heavier. Because of the extra weight they consume more power and can only go shorter distances when compared with the folding scooters. After about 10 or 15 miles it may be necessary to recharge the battery.
These electric, or battery-powered, motor scooters are often used to travel short distances around the neighborhood or perhaps on a school campus or other confined environment. They are particularly popular among the elderly, handicapped and disabled. Instead of being confined at home these elderly or handicapped people can now have some of their former independence returned to them. Motor scooters of this type are usually called mobility scooters.
Gas powered motorized scooters are usually more powerful and can attain higher speeds than the folding scooters or electric scooters. They can also travel longer distances when a larger fuel tank is included. Gas scooters may not be permitted in some areas so it is wise to check out the laws and regulations in your area before purchasing a motor scooter.
