Luxury sedans promise silence. They promise prestige. And they promise bills that make you check your bank account twice.
Drive a Mercedes E-Class. Sit in a BMW 5 Series. Feel the weight of that badge. It’s great until you need a new alternator, a fresh set of tires, and a software update that costs more than your grocery run. German engineering is brilliant. But it’s also expensive to keep alive.
Japanese luxury takes a different path.
It doesn’t chase the latest tech gimmick. It focuses on engineering that survives the test of time. There is a sedan that offers E-Class levels of space. It costs significantly less to own. It’s the 2020 Acura TLX (specifically the RLX platform, as Acura was transitioning branding, but the article refers to the RLX flagship). Wait, let’s stick to the source. The 2020 Acura RLX. It is the final model year of Honda’s luxury flagship.
It is fast. It is cheap. It is overlooked.
Why German Sedans Cost a Fortune to Own
The luxury formula used to be simple. Buy a badge. Enjoy the leather. Pay for the pain.
Depreciation hits German brands hard. CarEdge data shows five-year depreciation rates of 46-50% for Audi, BMW, and Mercedes. This sounds bad if you buy new. It’s a gift if you buy used.
Take the 2018 Mercedes-AMG E63. It cost $105,325 new. Today, it averages $49,300 used.
The 2020 BMW M55i dropped from ~$78,000 to $34,200 in three years.
The Audi A6 Prestige fell from $68,320 to $37,40.
But depreciation isn’t the only killer. Maintenance is.
RepairPal puts annual maintenance for the E-Class at $788. The 5 Series? $977. The A6? $913. Add in insurance, fuel, and the inevitable electronics failure, and the cost skyrockets. Modern luxury cars are full of turbos, mild-hybrids, and adaptive suspensions. Complex machines break complexly.
The 2020 Acura Rlx Space and Price Reality
Enter the 2020 Acura RLX.
It was Acura’s last true flagship sedan. It comes in two flavors: the gas-only RLX and the RLX Sport Hybrid.
Original prices were high. $54,900 base. $61,900 for hybrid.
Used prices are low.
Gas model average: $24,700.
Hybrid model average: $29,200.
Compare that to a 2020 Mercedes-Benz E-Class (base E 350), which ranges from $23,900 to $38,700 used. The price parity is striking. But the ownership experience is not.
E-Class Space vs. Acura RLX Space
People buy executive sedans for space. The Acura RLX wins this category comfortably.
Here is the breakdown:
* Cargo: The gas RLX offers 14.9 cu-ft. The E-Class offers 13.1 cu-ft.
* Front Legroom: The RLX gives 42.3 inches. The E-Class gives 41.7 inches.
* Rear Legroom: This is where it matters. The RLX provides 38.8 inches. The E-Class provides 36.2 inches.
That is a massive difference in the back seat. The hybrid RLX loses some trunk space (12.0 cu-ft) due to batteries, but the rear legroom advantage remains. If you need backseat room, the Acura RLX is the clear choice over the E-Class.
Five-Year Ownership Costs: The Acura Rlx Wins
Let’s look at the hard numbers. Edmunds tracks the “True Cost to Own” over five years.
- Acura RLX Gas: $56,119 total.
- Acura RLX Hybrid: $57,816 total.
- Mercedes E-Class (E 350): $60,680 total.
- Mercedes E-Class (AMG E63): $101,307 total.
You save roughly $4,500 just by buying the standard RLX over the standard E-Class. And if you go AMG? You save $45,000.
Fuel costs are similar. The RLX Gas gets 23 mpg combined ($3,350/year). The E 350 gets 26 mpg ($2,950/year). The hybrid RLX hits 28 mpg ($2,750/year). Fuel isn’t the dealbreaker; maintenance is.
Reliability: Why the Acura Rlx Is a Smart Buy
Mercedes reliability is a gamble. Common E-Class issues include infotainment glitches, keyless entry failures, and wiring harness problems.
Edmunds estimates E-Class E 350 maintenance/repairs: $10,788 (maintenance) + $7,754 (repairs).
Total maintenance/repair burden: ~$18,500.
Now look at the Acura RLX.
* Gas model maintenance (5 years): $7,553.
* Gas model repairs (5 years): $2,722.
* Total: ~$10,275.
The hybrid RLX maintenance/repair cost is slightly higher due to battery complexity but still significantly lower than the German alternative. You could own two gas RLX s and still spend less on repairs than one E-Class.
KBB ratings back this up.
RLX: 4.5/5 rating. 83% recommendation.
E-Class: 4.2/5 rating. 77% recommendation.
Simple engineering beats complex electronics. Always.
Performance: The NSX-Inspired Sport Hybrid
Don’t mistake reliability for boring. The Acura RLX Sport Hybrid is quick.
It uses technology derived from the second-gen NSX supercar. That is not marketing fluff.
The setup:
* 3.5L V6 engine.
* Three electric motors (one in the transmission, two at the rear wheels).
* Sport Hybrid SH-AWD system.
This system sends torque independently to each rear wheel. It can overdrive the outside wheel while braking the inside one. It makes the car rotate through corners like it’s on rails. It’s natural. It’s precise.
- Gas RLX: 310 hp. 0-60 mph in 5.8 seconds.
- RLX Sport Hybrid: 377 hp. 0-60 mph 4.5–4.9 seconds.
Compare that to the E 350, which takes 6.1–6.5 seconds to hit 60. The RLX Hybrid is faster. It has supercar DNA. It feels composed on bad roads. It handles like a sports car dressed in a tuxedo.
Interior and Tech: Understated Quality
The Acura RLX interior doesn’t scream. It whispers quality.
You get:
* Soft Milano leather.
* Genuine wood trim.
* Brushed aluminum.
* A 14-speaker Krell audio system.
* AcuraWatch safety suite (adaptive cruise, lane-keep, blind-spot).
Yes, the dual-screen infotainment looks dated compared to a curved glass dash in a 2025 BMW. But the materials still feel expensive. The seats are comfortable. The screens work. You aren’t fighting with a glitchy OS. The E-Class interior is more dramatic, but the RLX has aged better. Less to break.
The Verdict: Who Should Buy the 2020 Rlx?
If you want a badge that opens doors in Monaco, buy German.
If you want space, reliability, and performance without the financial bleed, buy Acura.
The RLX Sport Hybrid is the hidden gem. It offers NSX-inspired handling for the price of a compact SUV. It is a sleeper. It is fast. It is roomy.
There are downsides. The hybrid battery replacement can cost $2,000–$4,000 down the line. You lose some “prestige” points for not having a Mercedes star. But those are minor costs compared to the $100,000+ total cost of owning a used AMG E-Class.
The Acura RLX is forgotten. It sold poorly. That’s why it’s a bargain. The used market is finally waking up to it.
Is it perfect? No.
Is it smarter than a high-mileage E-Class? Absolutely.
You get the space. You get the speed. You keep the money.
