Are Teslas actually better for the environment?
Are Tesla Electric Cars actually better for the environment versus alternative energy sources? Do electric cars have lower emissions, even if their energy comes from fossil fuels? Between electric, hydrogen, gasoline, diesel, and hybrids, which uses the least amount of total energy, from well to wheel? This video will analyze the entire energy equation, starting from the very source of the fuel, whether that’s petroleum, natural gas, or other energy sources. Featured in the video is a 1965 Convertible Bug powered with Tesla battery pack modules. The car uses five modules of the 16 total in a Tesla Model S or X battery pack, giving it approximately 100 miles of range, paired with a 102 horsepower electric motor, and a manual transmission! It’s the ultimate environmentally friendly car, with a reused Beetle matched with reused Tesla batteries. Check out the video for a full breakdown of the emissions related impact of gasoline vs electric cars.

How global rallycross supercars hit 60 mph in 1.9 seconds
Regulations limit them to 2 liter engines and 45 millimeter turbocharger restrictor plates, which ultimately are the two factors limiting power. The engines produce about 600 horsepower, and over 650 lb-ft of torque, rocketing these machines from 0-60 in as fast as 1.9 seconds. 1.9 seconds! If we do the math, 60 mph is equivalent to 88 ft per second. 88/1.9 = 46.3 ft/sec squared, or if we divided by 32.2, it means the cars accelerate at over 1.4 longitudinal g’s!! That’s faster than any production vehicle, regardless of how much it costs. So how do they achieve such mind blowing acceleration? First and foremost, you’ll need all wheel drive and an absurd power to weight ratio. With a minimum weight of 2921 pounds including the driver and all fluids, the vehicles are carrying less than 5 pounds of weight for every horsepower the engine produces. All wheel drive is obviously critical for maximizing acceleration, but it’s also important that the engine torque finds its way to the wheels with the most traction. To do this, plate and ramp style mechanical limited slip differentials are used front and back. A shallow ramp angle in an LSD will lock up more easily under throttle. With the differential locked up, torque goes wherever it finds grip. A steep ramp angle will provide little lock-up, or if it’s as steep as 90 degrees, no lockup.
