Поля лучше пометить final, тем самым исключив возможность их модификации извне


public Car(String modelCar, int speed) {
this.modelCar = modelCar;
this.speed = speed;
}

От хранения массива машин и лишнего цикла при определении победителя можно избавиться, если при вводе данных сразу вычислять победителя и хранить его в отдельной переменной, тогда программа будет требовать меньше памяти и работать быстрее

int maxSpeed = 0;

for (int i = 1; i <= 3; i++) {

String modelCar;
int speed;

System.out.printf("Введите название %d автомобиля:\n", i);
modelCar = scanner.next();

System.out.printf("Введите скорость %d автомобиля:\n", i);

while (!scanner.hasNextInt()) {
System.out.println("Ошибка ввода");
scanner.next();
System.out.printf("Введите скорость %d автомобиля:\n", i);
}

speed = scanner.nextInt();

while (speed < 0 || speed > 250) {
System.out.println("Ошибка ввода. Скорость должна быть от 0 до 250 км/ч.");
System.out.printf("Введите скорость %d автомобиля:\n", i);
while (!scanner.hasNextInt()) {
System.out.println("Ошибка ввода");
scanner.next();
System.out.printf("Введите скорость %d автомобиля:\n", i);
}
speed = scanner.nextInt();
}

cars.add(new Car(modelCar, speed));
}
for (Car car : cars) {
if (car.speed >= maxSpeed) {
maxSpeed = car.speed;
race.leader = car.modelCar;
}
}
System.out.println("Лидер: " + race.leader);
}
}

Логику с определением победителя лучше в этот класс перенести из Main, т.к. функциональность определения победителя больше к классу Race относится


String leader = "";

ArrayList<Car> cars = new ArrayList<>();


}
