809 is the 2019 Mercedes-Benz E-Class, while 800 is the 2020 Mercedes-Benz E-Class. These two models have some differences in exterior design, powertrain, and configuration pricing. The relevant details are as follows: 1. The E-Class is a mid-size luxury sedan under Mercedes-Benz, competing with models like the BMW 5 Series and Audi A6L. The 2020 E-Class is equipped with three engines: a 1.5-liter turbocharged engine, a low-power 2.0-liter turbocharged engine, and a high-power 2.0-liter turbocharged engine. 2. The 1.5-liter turbocharged engine delivers 184 horsepower and 280 Nm of maximum torque, with a maximum power output at 6,100 rpm and peak torque between 3,000–4,000 rpm. This engine features a 48V mild hybrid system and uses an aluminum alloy cylinder head and block. 3. The low-power 2.0-liter turbocharged engine produces 258 horsepower and 370 Nm of maximum torque, with peak power at 6,100 rpm and maximum torque available from 1,800–4,000 rpm. It employs direct fuel injection and an aluminum alloy cylinder head and block. 4. The high-power 2.0-liter turbocharged engine generates 299 horsepower and 400 Nm of maximum torque, with peak power at 6,100 rpm and maximum torque between 3,000–4,000 rpm. It also features a 48V mild hybrid system and an aluminum alloy cylinder head and block. All three engines are paired with a 9-speed automatic transmission (9AT).

As someone who frequently drives various car models, I've found that the most fundamental difference between the Mercedes 800 and 809 lies in their engine performance. The 800, typically an entry-level model from the 1980s, was equipped with an old-fashioned 4-cylinder engine producing just over 100 horsepower. It struggled with hill climbs, had sluggish acceleration, and felt breathless on highways. The 809, an upgraded version from the 1990s, featured a 6-cylinder engine capable of over 150 horsepower, delivering much quicker response and effortless overtaking. Noise levels also improved significantly – the 800's engine compartment buzzed noticeably, while the 809 offered better sound insulation for more comfortable long-distance driving. Additionally, the 809 had superior suspension tuning, providing greater stability on bumpy roads. In terms of fuel consumption, the 800 could gulp down 10 liters per 100 kilometers, whereas the optimized 809 reduced this to 8 liters, being both eco-friendlier and more economical. Modern cars emphasize driving smoothness, and the evolution of the 809 makes the old 800 pale in comparison.

From a practical perspective, driving these two cars reveals significant differences. The 800 has limited space, with the rear seats barely accommodating two adults, and the trunk struggles to fit a large suitcase. The 809, on the other hand, is designed more spaciously, resembling a compact SUV, allowing passengers to stretch their legs comfortably—ideal for family trips. Safety features vary greatly: the 800 only offers basic seatbelts without standard airbags, while the 809 includes dual airbags and an ABS system, providing stronger protection in collisions. Maintenance-wise, finding parts for the 800 is difficult and expensive, whereas the 809 has a simpler structure, making tasks like replacing filters or spark plugs easier. Economically, the 800 has lower resale value and troublesome annual inspections, while the 809 holds its value better and offers hassle-free daily use. Overall, the 809 upgrades practicality, while the 800 remains a classic but struggles to keep up with modern lifestyles.

For design-focused fans like me, the 800 follows a retro style with boxy, angular lines and traditional halogen headlights that aren't bright enough for night driving. The 809 has a more modern, streamlined body with LED headlights that provide better illumination at night while being energy-efficient. The interior materials have also been upgraded - the 800 uses basic plastic dashboard that feels rough, while the 809 features leather seats with soft padding for added comfort. Technological features stand out: the 800 comes with a cassette radio, whereas the 809 has a CD player and a basic navigation screen. In terms of handling, the 809 responds quicker, while the 800's steering feels heavier. Younger generations tend to choose the 809 for its strong sense of fashion; those nostalgic may prefer the 800 for its unique charm, though it's outdated.
