Gasoline Cars Versus Electric Cars

the cost of operasting a tesla is now well below the cost of operating a gas based vehicle.  right now, it is a lovely car for applications based on urban commuting.  It is not a lovely solution for any form of range driving because charging is not ubiquious.

when your business demands random trips, it is a lousy solution still.

Yet i do not think that this will be forever.  The press is on to overcome it all.  Understand that we have matched normal range.  now imagine the EV simply doubling its range and shifting to a much cheaper battery tech.  all this is possible and close nat hand.

At that point, the gas car is totally toast.  what we do have is usuable but not quite over the top.

Gasoline Cars Versus Electric Cars

September 11, 2023 by Brian Wang

There are some people observing that gasoline has 12700 watt hours per kilogram vs EV batteries with 160 to 450 watt hours per kilogram. Gasoline needs to have an engine and gas tank and other parts to make the vehicle do anything. The battery pack of an electric vehicle is most of the mass of an electric car while the gasoline engine weighs far more than the electric motors.

The Tesla Model Y weighs between 3,920 and 4,416 pounds. The 2023 Toyota RAV4 CRUISER (AWD) HYBRID weighs 3,869.1 lbs. The Tesla Model Y comes in a few variations, including a Long Range and Performance dual-motor trim. Both trims weigh 4,416 lbs. The Model Y with the optional third-row seating weighs the most.

The 2023 Toyota RAV4 has a 14.5 gallon gas tank and can travel up to 595 miles on a single tank of gas under ideal conditions. The hybrid model has an EPA-estimated range of 580 miles. The regular RAV4 has an EPA-estimated range of 507 miles. The Tesla Model Y long range has 330 miles of range.

Currently in California, gas is $5.50 per gallon. 480 gallons per year is $2640 per year. The US average is 489 gallons/year per registered vehicle to go about 14,200 miles. Many Tesla’s and electric cars can be charged at home for about twelve cents per kWh. Tesla get about 4 miles per kWh. The 14200 miles would need about 3550 kWh. Supercharging or using other chargers can cost more at $0.25 to $0.50 per kWh. This is only needed about 10-20% of the time for most drivers. This means about $400-600 per year for the electricity. This would be free if the person has installed solar. The hardware costs for the solar power, battery and charger would be amortized over the years of usage. The electric cars need less maintenance. There is no need for oil changes and a lot of the other service.

The fuel and maintenance is about $2500-3000 per year less for the Tesla Model Y.

The insurance costs can be higher for the electric because of higher repair costs. This could be $1000 per year more for the Tesla.

The Tesla Model Y is a leader among electric SUVs, electric cars and is now the top selling car of any kind (gas or electric). It features an electric motor that produces up to 456 horsepower, while the Toyota RAV4 Prime offers 302 horsepower through its hybrid system. The power disparity between them shows clearly in the acceleration times. The Model Y can reach 60 mph from zero in just 3.5 seconds compared to the RAV4 Prime’s time of around six seconds. The Model Y’s top speed is also higher, clocking in at 155 mph compared to the RAV4 Prime’s 120 mph in electric-only mode. The instant torque and more responsive acceleration of the Model Y’s electric powertrain provide the performance that some drivers find exhilarating.

The price for a gas compact SUV to go from zero to 60 in 3.5 seconds is usually $100,000 or more. It has been common for gas car buyers to pay substantial premiums for sportier cars with very good acceleration and higher top speeds.

The Tesla Model Y has state-of-the-art technology features that better than the Toyota RAV4 Prime. The Tesla Autopilot is one of them. It uses cameras and radar, and advanced sensors, to control the steering, braking, and throttling of the vehicle on the road. It sports a larger and more responsive infotainment touchscreen and a mobile app integration that provides remote vehicle controls like unlocking, starting, and climate control. It has over-the-air software updates, voice-activated controls, and a more advanced sound system. The connectivity features available on the Model Y help access internet streaming, calendar integration, and traffic updates. In comparison, the RAV4 Prime doesn’t include most of these. The few available are optional extras.

The RAV4 Prime has 33.5 cubic feet of cargo capacity. The Model Y has 30.2 cubic feet of storage when the rear seats are up. With the rear seats folded down, the Model Y offers 72.1 cubic feet versus the 69.8 cubic feet of the RAV4 Prime. The Model Y has a front trunk that provides an additional 4.1 cubic feet of storage. This feature makes the Model Y more practical for those who require extra space for luggage or equipment. Overall, the Tesla Model Y provides 76.2 cubic feet of space to the RAV4 Prime’s 69.8, when the rear seats are folded down, and the front trunk is added.
