In the second quarter,
link hidden, please login to view’s electric vehicle sales in the United States again surpassed General Motors, ranking second in the U.S. electric vehicle market sales, and is on track to close the gap with Tesla.

In the second quarter of this year, Ford sold 23,957 electric vehicles in the United States, a 61% increase from the same period last year, when total electric vehicle sales were 14,843. Meanwhile, Ford’s sales of hybrid vehicles rose 55 percent year over year. However, sales of internal combustion engine cars were down 5 per cent year on year.
Ford saw double-digit sales growth for several of its electric vehicles. Sales of the Ford F-150 Lightning rose 76.9% to 7,902 units. While new competitors such as the Tesla Cybertruck and the Chevrolet Silverado EV RST have all hit the U.S. market, the Ford F-150 Lightning remained the best-selling electric truck in the U.S. in the first half of the year, with 15,654 units sold.
Second-quarter sales of the Ford Mustang Mach-E were up 46.5% year-over-year to 12,645 units. In the first half of this year, 22,234 units of the Mustang Mach-E were delivered, the best performance ever. Sales of Ford’s E-Transit electric van continued to climb in the second quarter, rising 95.5 percent to 3,410 units from a year earlier.
In the first half of 2024, Ford sold a total of 44,189 electric vehicles in the U.S. market, up 72% from 25,709 in the same period last year.
Ford CEO Jim Farley said the automaker is shifting to smaller, more affordable electric vehicles to close the gap with Tesla and fend off competitors like BYD worldwide. Referring to Americans’ love affair with “larger vehicles,” Farley said smaller electric vehicles are “very important to driving the decarbonisation of American society and the development of electric vehicles.”
Ford’s surge in electric vehicle sales in the US market is enough for it to continue to overtake General Motors. In the United States, GM delivered 21,930 electric vehicles in the second quarter, compared with 38,355 in the first half of 2024.
GM is also ramping up production by introducing new models, with electric models such as the Chevrolet Blazer, Equinox and Silverado coming to the U.S. market. While Tesla did not give specific sales figures by region, its second-quarter electric vehicle sales worldwide exceeded expectations, delivering 443,956 electric vehicles and remaining №1 in the U.S. market.
As competition in the U.S. electric vehicle market intensifies, other competitors, including Hyundai and Kia, also set new EV sales records in the second quarter. Hyundai Motor, for example, set a new sales record with its IONIQ 5 model, which sold 18,728 units in the first half of the year. Meanwhile, sales of Kia’s first three-row electric SUV, the EV9, are also climbing.

f you read automotive articles on a regular basis, you’ve no doubt read about the scientific side of brakes many times. They convert kinetic energy, which is the energy of motion, into heat energy through friction between the brake linings and the drum or rotor. Because of this, brakes get hot…real hot…and dissipating the heat is one of the most critical factors affecting brake operation.
So, would you believe that shock absorbers work off the same scientific basis of converting kinetic energy into heat energy? It’s true, and here’s how it works.
Kinetic energy is the energy of motion. The springs on a vehicle support the weight of it and allow the suspension to move. But what would happen if there were no shock absorbers? Every time you hit a bump, the springs would compress then expand, and do this over and over again until they finally settled down.
If you’ve never experienced the sensation, which is something like rocking on a boat, you’ve likely seen it on a car going down the road. The front or rear goes up and down, up and down, literally “bouncing” down the road. It happens, in this case, not due to the lack of shocks, but due to the fact that they are simply worn out, so for all practical purposes, they may as well not exist.
link hidden, please login to view The springs absorb the kinetic energy from hitting a bump, but since springs are considered elastic objects, the energy is turned into potential energy. And, in the case of a spring, or any elastic object, the potential energy is then released, and the energy output equals the energy input. The spring will return to its original shape. At that point, the momentum of the car body creates kinetic energy, which in turn acts on the spring in the opposite direction. As you can see, this is a vicious circle, and we need shock absorbers to control it.
The job of a shock absorber is therefore to control the kinetic and potential energy of a spring by dampening its movement. Shock absorbers are filled with hydraulic oil, separated between two different chambers. Between the two chambers is a piston and valve assembly. (See Figure 1). The piston is connected to a piston rod which moves in and out of the shock as the suspension moves.
Compression is when the piston rod is forced into the shock; rebound is when the piston rod is pulled back out. The key lies in the valving, which restricts the flow of oil between the two chambers. Forcing the oil through these valves creates friction, which in turn creates heat. Yes, shocks do get hot, and now the shock has turned kinetic energy into heat energy.
Changing the size of these valves changes the amount of force it takes for compression or rebound, which ultimately changes the ride characteristics of the vehicle. This is one of the main reasons there’s a difference in feel between a sports car and a luxury car.
The more restrictive the compression and rebound, the less the suspension spring will move, which provides improved handling and stability characteristics, such as those desired on a sports car, but this also results in a firmer ride. Less restrictive compression and rebound allows greater spring movement and a softer ride, but not as good handling characteristics. There’s always a tradeoff.
The comparison between the compression and rebound forces in a shock absorber is the shock ratio. Many standard shocks have a 50/50 ratio, meaning the compression and rebound forces are equal. Unequal forces one way or the other can have a drastic effect on handling, and one of the best examples to demonstrate this is with some old school drag racing tech. In drag racing, it’s important to shift the weight to the rear of the vehicle to increase traction while launching. One of the ways to attain this is by using 90/10 shock absorbers on the front.
What this means is that of the total compression and rebound forces, 90% of the force is required to compress the shock, but only 10% of the force is required to extend the shock. When launching, the front of the car wants to lift as weight shifts to the rear. With a 90/10 shock, the front will unload easily and allow the weight to shift to the rear. Then, since it takes a much greater force to compress the shock, instead of the car coming right back down and bouncing in the front after hitting the track, the shocks will remain extended with the weight shifted rearward, and slowly settle as the car goes down the track.
It often takes a while and a few different adjustments with shock ratio, both front and rear, to get a drag car suspension properly “tuned” in. By the same token, stock vehicles, either performance or luxury, are engineered to find the best of both worlds in handling versus comfort. So, the next time you talk about shocks to your customer, make it fun and talk a little science.
