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

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

Не рекомендую писать бесконечные циклы через while (true) - лучше всегда явно прописывать условие выхода из цикла, чтобы уменьшить вероятность ошибиться и повысить читабельность кода

System.out.println("— Введите марку машины №" + i + ":");
name = scanner.next();

if (name.isBlank()) {
System.out.println("Укажите марку машины!");
} else {
while (true) {

Код для считывания скорости с ввода лучше вынести в отдельную функцию - код, разделённый на небольшие функции, легче читать, поддерживать и переиспользовать

System.out.println("— Введите скорость машины №" + i + ":");
if (scanner.hasNextInt()) {
speed = scanner.nextInt();
if (speed <= 0 || speed > 250) {
System.out.println("Укажите скорость от 0 до 250!");
} else {
break;
}
} else {
System.out.println("Введите значение!");
scanner.next();
}
}
break;
}
}
Car car = new Car(name, speed);
System.out.println("Самая быстрая машина: " + race.returnLeader(car).name);
}
scanner.close();
}
