Hello everyone, I have a question regarding the W210 E55 I don't own one, but I've been thinking of getting one, so I have a few questions that I would appreciate your knowledge on The E55 would be a little bit over 3k rpm at 100mph and a bit under 4k at 120mph ( I'm not exactly sure about this since this is what I got from the internet) So would it be fine for cruising at such high rpm, for example 30-40 miles daily? Or should I go for a 2008-2009 E550 which would be more expensive but with the 722.9 that would be slightly under 2500rpm for 100mph and 3k for 120mph I would appreciate your input regarding this
I have multiple cars and drive them often and have never felt the RPM's being high but then again, I dron't drive my cars 120+ miles/hour daily either so yeah, that's my answer.

Yeah I know that 120 is a bit too much daily but whenever the road allows it I am sure I would go for it hence my question would the engine be fine at such rpm cruising between 3k to 4k?
Highway speeds are easy on an engine at steady cruising: no accelerating, great cooling, steady rpms
it's an easy task for either vehicle you're debating between. The only things to consider are fuel, noise vibration and harshness, but not necessarily wear and tear. It also will depend on the health of the engines in each get and how they are maintained. More driving at 120mph, more maintenance especially oil changes.
that being said, here is ChatGPT:
When comparing the W210 E55 (1998–2002) with the 2008–2009 E550, especially in terms of cruising RPMs at higher speeds, it comes down to a few factors that affect comfort, performance, and longevity.
The W210 E55 AMG comes with a 5.4L naturally aspirated V8 paired with the 5-speed automatic transmission (722.6), and as you’ve mentioned, at higher speeds like 100 mph or 120 mph, you’ll likely see the RPMs sitting between 3k and 4k. This transmission has fewer gears, so it tends to run at higher RPMs at highway speeds compared to newer models with more advanced gearboxes.
A few things to consider about cruising at higher RPMs:
1. Engine Wear: The M113 engine in the E55 is robust and can handle higher RPMs without issues, but prolonged cruising at 3,500–4,000 RPM can accelerate wear over time. However, this engine is known for its durability.
2. Fuel Consumption: Running at higher RPMs will increase fuel consumption, which could add up if you’re driving 30–40 miles daily at high speeds.
3. Comfort: At higher RPMs, there will be more engine noise and potentially a bit more vibration, which could affect overall comfort on long highway drives.
The 2008–2009 E550, on the other hand, comes with the 722.9 7-speed automatic transmission, which allows for much lower RPMs at similar speeds. The lower RPMs (around 2,500 at 100 mph) will translate to better fuel efficiency, reduced wear on the engine, and a quieter, more comfortable ride at high speeds.
Verdict:
• W210 E55: If you’re a fan of the older AMG character and performance, the higher RPMs at speed shouldn’t be a deal-breaker. The car can handle it, but fuel economy and long-term wear could be concerns if you plan to do this kind of driving regularly.
• 2008–2009 E550: If you prefer more modern comfort, better cruising fuel efficiency, and less wear on the engine, the E550 is a better choice, though it’s more expensive.
Ultimately, if cruising regularly at high speeds is important to you and comfort is a priority, the E550 with the 722.9 might be the better choice. If you prefer the character and performance of the W210 E55 and are okay with the higher RPMs, it’s still a solid car that can handle those speeds.

Here's a photo of the speedometer and tachometer in my W210 E55. Did this for 450 miles (725 kilometers) each way from Kerrville to El Paso County line and back.

Yeah from what I got from others on reddit is that these cars are made to handle high speeds despite the high rpm
