What are the differences between Audi A4 and S4?

[McCarmen]

Here are the differences between Audi A4 and S4: 1. The Audi A4 is the base model for the S4, which has more power, is all-wheel drive, and is an upgraded version with a sports suspension. 2. The exterior dimensions of the Audi A4 and S4 are different: (1) The A4's exterior dimensions are 4750X1842X1433mm with a wheelbase of 2828mm. (2) The S4's exterior dimensions are 4749X1842X1400mm with a wheelbase of 2831mm. Here is some related information: 1. The S4 comes with 18-inch aluminum alloy wheels, tire specifications 245/40R18, and can also be equipped with larger 19-inch wheels. 2. The S4's engine, chassis, suspension, gears, and seats are all designed for sportiness, making it cooler, more stylish, and younger than the A4.

I usually commute to work in an Audi A4, and honestly, it's quite different from the S4. The A4 uses a 2.0T engine, which provides a smooth and comfortable ride with a fuel consumption of just over 8 liters per 100 km, making it ideal for daily commuting. The S4, on the other hand, is a different beast. Its 3.0T six-cylinder engine is downright brutal—stepping on the gas feels like getting kicked, and the acceleration is exhilarating. However, the trade-off is significant: fuel consumption doubles to 15 liters per 100 km, adding several hundred yuan to the monthly fuel bill. Additionally, the S4's suspension is much stiffer, making speed bumps uncomfortable, and the rear seats aren't as ergonomic as the A4's. Unless you're truly passionate about high-speed driving, spending over 200,000 yuan more on the S4 isn't really necessary.

Just test drove the S4 last week - this car drives performance enthusiasts wild! The stock 354 horsepower needs no modifications, stomping the throttle pins you to the seatback. The magnetic ride suspension is terrifyingly stable in corners, while the brake calipers can plant the car instantly. Most impressive is the dynamic steering system - just half a turn of the wheel whips the nose around, far more agile than a regular A4. Even the exhaust is specially tuned, with satisfying pops on downshifts - driving through tunnels with windows down is pure joy. Though the bucket racing seats deserve criticism - they kill your back on long drives. The regular A4 seats are still better for daily comfort.

At first glance, the A4 and S4 differ like a business suit versus sportswear. The A4 boasts elegant lines, a standard chrome grille, and 17-inch wheels exuding executive vibes. The S4 looks far more aggressive with its honeycomb black grille, silver mirror caps, and red brake calipers peeking through 19-inch alloys. The contrast intensifies inside: the A4 features wood trim with light leather, while the S4 sports carbon fiber accents hugging bolstered seats with extendable thigh support – even the seatbelts come in vibrant red. A word to potential S4 buyers: the silver grille frame and quad exhaust tips are prone to scrapes. My neighbor dented his exhaust pipe just three days after delivery.

If you're on a tight budget, I highly recommend the A4. The base model can be had for just 300,000 yuan out-the-door, and it runs fine on 92-octane fuel. But the S4 starts at 500,000 yuan, requires 98-octane gas, and even a single tire change costs 800 yuan more than the A4. The daily driving cost difference is even more significant: an A4 service costs 1,200 yuan while an S4 oil change starts at 2,000 yuan; the A4 gets 9L/100km in city driving versus the S4's easy 16L/100km; the insurance gap is ridiculous - one year of S4 coverage equals three years for the A4. Though the S4 is two seconds quicker in acceleration, unless you're tracking it daily, the 200,000 yuan saved could be better spent on travel or investments.

To put it bluntly, the difference between these two cars lies in their DNA. The A4 is based on a modified front-engine, front-wheel-drive platform with all-wheel drive, which is perfectly adequate for city driving. The S4, however, is built on a proper longitudinal engine platform, with a driveshaft directly connected to the rear axle and a Torsen differential for pure mechanical all-wheel drive, offering significantly better traction in rain or snow. The engines are no comparison either—the EA888 four-cylinder versus the EA839 six-cylinder, with a horsepower gap of over 100. Although both have 8-speed automatic transmissions, the S4's gear shifts are tuned to racing levels. Even the exhaust valves are active, producing a supercar-like roar in sport mode. So don’t be fooled by the similar exteriors—once you drive them, you’ll realize they’re completely different cars.
