Переменные можно пометить final и убрать геттеры с модификатором private - тогда можно будет иметь такой же надёжный и безопасный доступ к данным по имени переменной

public Car(String name, int speed) {
this.name = name;
this.speed = speed;
}
public String getName() {
return name;
}
public int getSpeed() {
return speed;
}
public int mileage() {
return 24 * 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

Race race = new Race();

for (int i = 0; i < cars.length; i++) {
System.out.println("Автомобиль " + (i + 1) + ":");

String name;
while (true) {
System.out.println("Введите название автомобиля: ");
name = scanner.nextLine().trim();
if(!name.isEmpty()){
break;
}
System.out.println("Ошибка: название автомобиля не может быть пустым!");
}

int speed = 0;
while (true) {
System.out.println("Введите скорость автомобиля (1-250 км/ч): ");
if (scanner.hasNextInt()) {
speed = scanner.nextInt();
scanner.nextLine();
if (speed > 0 && speed <= 250) {

Минимальную и максимальную скорости лучше вынести в константы для повышения читабельности кода

break;
} else {
System.out.println("Скорость должна быть от 1 до 250.");
}
} else {
System.out.println("Введите целое число");
scanner.next();
}
}

cars[i] = new Car(name, speed);
}
}

Car winner = race.raceWinner(cars);
System.out.println("Самая быстрая машина: " + winner.getName());
}
}
