The Most Powerful Sedans You Can Buy Right Now, Ranked by Horsepower

If you are asking which powerful sedans offer genuinely impressive acceleration, the short answer is that four stand apart right now — and they are not close to each other. Ranked by horsepower, they run from 668 to 1,234 hp, and from $98,900 to $249,000. Every figure below comes from the maker’s own US site, checked on the day this article was written, because second-hand price lists for these cars disagree with each other by thousands of dollars. Acceleration times are the makers’ own claims, not independent test results.

The ranking at a glance

• Lucid Air Sapphire — 1,234 hp, 0–60 mph in 1.89 seconds, $249,000 fully equipped.
• Mercedes-AMG GT 63 S E Performance 4-Door — 831 hp, 0–60 mph in 2.8 seconds, $200,500 MSRP.
• BMW M5 — 717 hp, 0–60 mph in 3.4 seconds, $123,300 starting MSRP before destination and gas-guzzler tax.
• Cadillac CT5-V Blackwing — 668 hp, 0–60 mph in 3.4 seconds, from $98,900 before destination.

All four live in our Sedans coverage. Horsepower decides this order, but it is not the whole story — the cheapest car here is barely slower to 60 mph than the one costing twice as much, and the reasons why matter more than the ranking itself.

1. Lucid Air Sapphire — 1,234 hp

• Power: 1,234 hp, three electric motors
• 0–60 mph: 1.89 seconds (Lucid claim)
• Price: $249,000 fully equipped
• Range: up to 427 miles EPA-estimated

The Sapphire is the outlier in every direction. Three motors — one at the front, two at the rear — with torque vectoring between the rear wheels, and a claimed 1.89-second sprint that no gasoline sedan here can touch. The surprise is that it is not a stripped-out special: Lucid quotes up to 427 miles of EPA-estimated range and a 205 mph top speed in the same car. Day to day, that combination means violent speed without the usual penalty of stopping to charge every couple of hundred miles.

The catch is the price, and what it does not include in the conversation. At $249,000 it costs roughly double the BMW below, for a sprint-time advantage you can only use in brief, empty-road bursts. It is the right answer if the question is purely “how fast can a sedan go,” and a harder one to justify if the question is “how fast do I need a sedan to go.”

2. Mercedes-AMG GT 63 S E Performance 4-Door — 831 hp

• Power: 831 hp, hand-built 4.0-liter twin-turbo V8 plus electric motor
• 0–60 mph: 2.8 seconds (Mercedes-Benz claim)
• Price: $200,500 MSRP
• Torque: 1,032 lb-ft

Watch the name, because AMG sells two cars that sound almost identical. The 805-hp figure you will see quoted elsewhere belongs to the two-door GT coupe. The four-door tested here makes 831 hp and 1,032 lb-ft, and Mercedes-Benz claims 2.8 seconds to 60 mph. It is a hybrid, but not the kind you buy to save fuel: the electric motor exists to fill in torque while the V8 spools up, and the result is the hardest shove of any gasoline car on this list.

As a daily car it is the most complete luxury item here — four doors, a real back seat, and a cabin finished like a flagship. The trade is money in both directions: $200,500 is the starting price, not the price of the car most buyers take home, and a twin-turbo V8 hybrid of this size will never be cheap to run. Buy it for the combination of speed and occasion, not for value.

3. BMW M5 — 717 hp

• Power: 717 hp, twin-turbo V8 with an electric motor
• 0–60 mph: 3.4 seconds (BMW claim)
• Price: $123,300 starting MSRP; $126,850 with destination and gas-guzzler tax
• Torque: 738 lb-ft

The M5 is the usable one. A twin-turbo V8 paired with an electric motor, all-wheel drive, four doors, and a trunk — the formula has not changed, even though the powertrain has. BMW claims 3.4 seconds to 60 mph, which is a tenth off the Cadillac below despite nearly 50 extra horsepower, and that gap tells you something useful: beyond a certain point, traction and weight matter as much as output.

Two pricing notes, because this is where buyers get surprised. First, BMW USA now lists the 2027 M5 — the 2026 figures floating around second-hand listings are last year’s car. Second, the $123,300 headline is before the $1,450 destination charge and a $2,100 gas-guzzler tax, which BMW’s own configurator totals at $126,850. Still, at roughly half the Lucid’s price, the M5 is the car on this list most people with this budget would actually live with every day.

4. Cadillac CT5-V Blackwing — 668 hp

• Power: 668 hp, supercharged 6.2-liter V8
• 0–60 mph: 3.4 seconds (Cadillac claim)
• Price: from $98,900, before destination
• Gearbox: 6-speed manual standard, 10-speed automatic available

The Blackwing is the only car here that feels like it was built by people who drive for fun. Rear-wheel drive, a standard six-speed manual in a segment where manuals have all but vanished, and a hand-built supercharged V8 making 668 hp. Cadillac claims the same 3.4-second 0–60 time as the M5, from 49 fewer horsepower, which is what rear-wheel-drive traction and a lighter brief will do for you.

It is also the only entry under $100,000, and the only one that asks something of its driver: 668 hp through the rear wheels alone demands respect in bad weather, and there is no electric motor smoothing out the delivery. If you want involvement over insulation, this is the pick. If you want a sedan that does the fast part for you, look at the three above it.

Which one should you actually buy?

Start with the budget, because it separates this list cleanly. Under $100,000, there is one answer: the Blackwing. Around $125,000 all-in, the M5 is the all-weather, everyday answer. Past $200,000, the choice is philosophical — the AMG if you want a hybrid V8 flagship, the Lucid if you want the outright fastest sedan on sale and never want to visit a gas station again. If none of these fit because you need room, running costs, and sanity first, our best family sedans for 2027 ranking is the practical version of this question. And if you are weighing any of these prices against a monthly payment, the loan calculator in Car Tools will show what the sticker actually costs per month.

One last distinction worth keeping: this list ranks power, not greatness. Our Top 5 performance cars piece judges cars on the whole package — handling, character, and value alongside speed — and reaches different conclusions. Power gets you the headline. The rest of the car decides whether you still love it a year later.

Frequently Asked Questions

Is the most powerful sedan also the quickest? Usually, but not by as much as the horsepower gap suggests. The 1,234-hp Lucid is quickest here at a claimed 1.89 seconds, yet the 668-hp Cadillac matches the 717-hp BMW at 3.4 seconds. Traction, weight, and how power is delivered matter as much as the headline number.

Are these prices what you actually pay? No. Every price above is the maker’s starting figure before destination charges, taxes, options, and dealer fees — except the Lucid, which is listed fully equipped. The BMW is the clearest example: $123,300 becomes $126,850 once destination and the gas-guzzler tax are added, before a single option.

Which of these is best for daily driving? The BMW M5, for most buyers: all-wheel drive, four doors, and a hybrid system that takes the edge off town driving. The Blackwing is the most rewarding daily if you drive a manual and live somewhere dry. The Lucid and AMG are the special-occasion answers — extraordinary, but priced like it.
