In 2050 cars are likely to be heavily autonomous, highly connected and even heavily electric and integrate seamlessly into everyday life.
Cars in 2050 and beyond will often be more than just transportation and may even offer and have features like entertainment spaces mobile offices and sleeping quarters although it may be that cars are just still cars and just have more features in 2050.
In 2030 cars will look the same as they do as of now but the cars of 2030 will be more personalized, more connected as well as autonomous and have a focus on hybrid and electric power.
The traditional car shapes may become less common in 2030 and standard features in cars in 2030 and beyond may include high speed WiFi, wireless charging and car to car communication.
The reason why electric cars are not the future is because they are not a good option for everyone and cannot travel long distances without needing to stop and charge for hours.
Electric vehicles can only travel so far before they require charging and some may only go as far as 250 miles to 300 miles before they need charged again and the charging takes hours to get a full charge.
Unlike gasoline cars that require just adding gasoline to the car to keep going.
Also charging stations for electric vehicles are not at all locations either.
And there are also concerns about the environmental impact of the production and disposal of electric vehicle batteries and electric cars also tend to cost more than gas powered vehicles.
The electric vehicle batteries also have a short life when compared to the capacity of fuel and they take forever to recharge.
Also when the electric car battery goes bad it can cost $13,000.00 or more to replace.
Electric cars do also have transmission fluid but it's different than a gasoline car transmission and transmission fluid.
Electric cars have single speed transmissions and do have transmission fluid to keep it lubricated and cooled.
The EV transmissions use E transmission fluids which protect the bearings and gears in the e transmission which is a single speed transmission in most electric vehicles.
The E transmission fluids also play a critical role in cooling the electric motor by dissipating the heat that is generated by the operation of the EV motor.
The reason why electric cars do not need oil is because the electric cars use electric motors and not internal combustion engines.
Internal combustion engines need full lubrication for the internals of the engine including the bearings, rods, camshaft, crankshaft, valves, lifters etc.
However electric motors only have the bearings that need lubricated so they have sealed bearings at the ends of the electric vehicle motors shafts which don't require any further lubrication or oil changes.
EV motors are lubricated with specialized lubricants which include e-greases and e-fluids for the lubrication and thermal management.
The lubricants used in EV motors protect the gears, bearings and other critical components from wear and friction and electrical damage and also helps to dissipate heat that is generated by the EV motor.
The E fluids are made for both cooling and lubrication and the e greases mainly focuses on high speed bearing protection and electrical insulation.
EV lubricants are often formulated with synthetic base oils like polyalphaolefins or PAOS or esters.
The EV motor bearings are sealed and don't require any additional grease or oil.
The EV transmissions use E transmission fluids which protect the bearings and gears in the e transmission which is a single speed transmission in most electric vehicles.
The E transmission fluids also play a critical role in cooling the electric motor by dissipating the heat that is generated by the operation of the EV motor.
EV or electric car and electric vehicle motors they don't require engine oil like a gasoline or diesel engine needs oil as they don't have the complex moving parts like internal combustion engines do such as crankshafts, engine bearings, rods etc that need the lubrication constantly.
However electric car motors do have oil in the bearings that are sealed but they don't need anymore oil or oil changes like an internal combustion engine needs.
Electric car and electric vehicle motors have sealed bearings which are designed for a long life.
