Insurance premiums for performance and luxury cars have climbed into territory once reserved for mortgage payments. Three 2026 studies from The Zebra, CarInsurance.com and Compare.com each ranked the models that cost drivers the most to cover. Here are eleven cars that top those rankings, starting with the BMW M5 and ending with the Cadillac CT4-V.

1. BMW M5: Rate Leader
The Zebra’s 2026 ranking puts the BMW M5 at the top, with an average full-coverage premium of $7,819 a year for full coverage. That figure is a national average built from ZIP-code rate filings, so individual quotes move with address and driving record.
At nearly eight thousand dollars a year, the M5 sits at the peak of this list. Owners shopping the car should price coverage before signing the purchase paperwork, because the insurance line can rival a second car payment for some households.
2. Audi S8: Quiet Money Pit
Audi’s long-wheelbase super sedan lands second on The Zebra’s list, averaging $7,069 a year to insure. The S8 pairs a twin-turbo V8 with a limousine-sized body, a mix that insurers appear to treat as costly to repair and costly to replace, per this second-place Zebra ranking.
Only a few hundred dollars separate it from the M5 at the top. Buyers drawn to the understated look should know the premium is anything but understated, and comparing several carriers is the most practical way to trim it.
3. Mercedes-Benz S-Class: Luxury Tax
The Mercedes-Benz S-Class averages $6,574 a year, which makes it the priciest non-performance luxury sedan in The Zebra’s 2026 data. Its rivals above it on the table are all sold on speed, so the flagship Mercedes earns its place on size and sticker value alone.
Advanced driver aids and an expensive interior can make even a minor collision a large claim. Prospective owners should treat the premium as part of the car’s real cost, much like depreciation and routine service.
4. Lucid Air: Costliest Electric
The Lucid Air is the costliest electric car on The Zebra’s 2026 ranking, averaging $6,040 a year to insure, according to the full-coverage rankings. A high price and a small-volume luxury build can make repairs and replacement costly compared with mass-market models.
EV shoppers often assume lower running costs end at the charger, yet the premium here cuts the other way. Anyone considering the Air should collect quotes early, since the spread between carriers on a niche luxury EV can be wide.
5. BMW M8 Gran Coupe: Top of a Different Table
CarInsurance.com’s 2026 study tops its table with the BMW M8 Gran Coupe, priced at $6,744 a year in its most expensive trim. The figures come from Quadrant Information Services rates, summarised in the CarInsurance.com study.
The four-door body does not soften the result, since insurers price the M8 on power, value and repair cost rather than doors. For a family needing rear seats, the Gran Coupe still carries a performance-car premium, and that detail belongs in the budget discussion.
6. Audi e-tron GT: Electric Speed Surcharge
The Audi e-tron GT is the most expensive electric car in CarInsurance.com’s study, at $6,291 a year for the RS performance version. That makes the trim, and not only the badge, the driver of the price, as laid out in the annual rate table.
The finding suggests that choosing a lower-output version of the same car could reduce the bill noticeably. Shoppers comparing e-tron GT variants should request quotes for each one, because insurers rate them separately.
7. Porsche 911 Turbo: Six-Month Sticker Shock
Full coverage on a Porsche 911 Turbo runs $3,200 for six months in CarInsurance.com’s rate survey, as listed in the rate survey results. Unlike most entries here, that number covers a half-year policy term rather than twelve months.
Doubling it gives a rough annual picture, though real quotes vary with driver history and location. The 911 Turbo combines high performance with expensive bodywork, a pairing that insurers consistently price at a premium.
8. BMW M4: Compare.com’s Number One
Compare.com’s July 2026 study of 58 million rate quotes ranks the BMW M4 first, at $6,380 a year, in its model-by-model analysis. The study looked at 257 new models, so topping the list means the M4 stood out from a very large field.
The coupe’s blend of power, a high price and costly repairs explains much of that result. Prospective owners can often narrow the gap by raising deductibles or bundling policies, though the M4 will likely stay near the top regardless.
9. Cadillac CT4-V: Costly American
The compact Cadillac CT4-V is the costliest American car in Compare.com’s study, at $5,542 a year, according to the Compare.com list. The figure is a median annual full-coverage cost drawn from 2025 and 2026 model-year applications between January 2025 and May 2026.
A compact sport sedan from a domestic brand might seem an easy insurance bet, yet the V-Series performance tuning changes that. Buyers cross-shopping against German rivals will find the premium gap is narrower than the badge suggests.
10. Mercedes-Benz G-Class: Boxy and Pricey
The Mercedes-Benz G-Class averages $5,501 a year of full coverage in Compare.com’s 2025 and 2026 model data, as shown in the Compare.com model data. Its tall, upright shape and very high purchase price both feed into the rate.
The truck-like body can cause heavy damage to other vehicles in a crash, something insurers weigh in liability pricing. Owners should expect the cost of protecting the G-Class to stay high for as long as it remains a luxury status vehicle.
11. BMW 7 Series: Flagship Tenth
BMW’s flagship sedan averages $4,730 a year, tenth among the 257 models examined in Compare.com’s list. The 7 Series closes out the ranking, noted in the Compare.com ranking, and still carries a premium well into four figures.
Large luxury sedans carry expensive technology, wide sensor arrays and costly body panels, all of which raise claim costs. Anyone considering a 7 Series should treat insurance as a standing budget item and shop quotes before choosing a trim.
