Not all rally cars are four-wheel drive. Most rally cars adopt four-wheel drive to cope with treacherous road conditions, but some rally cars also use rear-wheel drive. Rally cars are generally specially manufactured and equipped with safety features such as fire extinguishers, racing seats, and racing seat belts. The chassis of a rally car is a tubular space frame, which offers higher strength and can adapt to extremely harsh road conditions. The suspension system of a rally car is specially tuned and designed, with high-performance shock absorbers. The engine and transmission of a rally car are custom-made, featuring powerful engines with quick acceleration from 0 to 100 km/h, and the drivetrain is also reinforced.

I've been playing with racing cars for many years, and I've seen rallying change a lot. In the 1960s, many classic rally cars were rear-wheel drive or front-wheel drive, and cars like the Mini Cooper performed exceptionally well on small roads. Later, in the 1980s, the Group B era began, and four-wheel-drive cars like the Audi Quattro rose to prominence, making a huge impact. Nowadays, the WRC World Rally Championship is predominantly four-wheel drive. But rallying isn't all about four-wheel-drive cars. In local competitions, such as the British Rally Championship, there are specific two-wheel-drive categories where small cars like the Ford Fiesta can compete with just front-wheel drive, offering lower costs and easier modifications. On dry tracks, rear-wheel-drive cars can be more thrilling to control. The key is the competition rules—each event is open to different categories, and beginners can start with two-wheel drive to save on expenses. Of course, four-wheel drive has obvious advantages on muddy surfaces, but it's not a mandatory requirement.

As a rally enthusiast, I've watched various competitions and noticed this issue is quite common. Top-tier WRC events predominantly use all-wheel-drive vehicles to enhance traction on surfaces like snow or gravel. However, rally racing encompasses diverse formats – take vintage rallies where drivers thrash classic rear-wheel-drive cars like Porsche 911s with pure exhilaration. Local club events often permit front-wheel-drive entries due to simpler maintenance and lower barriers, ideal for budget-conscious beginners. Regulations dictate drivetrain configurations by class: Group R2 encourages FWD, while Group R5 mandates AWD. Thus, not all rallies require four-wheel drive. Safety-wise, AWD excels on slippery terrain, but two-wheel-drive cars outperform on dry tarmac while honing driving skills. Ultimately, it depends on the specific event type and vehicle classification.

I've participated in several amateur rally events, driving a modified front-wheel-drive compact car. While it doesn't grip as well as four-wheel-drive in muddy conditions, with good control you can still go fast. Rally isn't just about top-tier events; there are two-wheel-drive categories everywhere, like our local club's Classic series using rear-wheel-drive cars for off-road, which is budget-friendly and fun. WRC requires four-wheel-drive, but grassroots competitions are much more flexible. The key lies in driving skills – four-wheel-drive helps in mud, while rear-wheel-drive delivers more excitement on dry roads. The drivetrain affects performance but doesn't define the essence of rallying.
