Ferrari Roma vs Porsche 911 Turbo S: The Honest Buyer Guide

Start with what each car was designed to be, because that decides everything else. The Roma is Ferrari's take on the classic front-engine grand tourer: long hood, engine set behind the front axle, two seats plus a pair of occasional ones, and a shape that borrows from Ferrari's 1960s GT cars rather than its current supercars. It is built to cover distance beautifully and to feel like an occasion every time you open the door.

The 911 Turbo S was built to answer a different question: how fast can a car be while still working as normal transportation. Rear engine layout, all-wheel drive, a dual-clutch gearbox, and a chassis Porsche has been refining for six decades. The result is a car that will humble machines costing twice as much and then sit in traffic without complaint.

Neither is the better car. They are answers to different questions, and buyers get into trouble when they choose the one that sounds best rather than the one that matches how they actually drive.

The numbers are close enough to argue about and far enough apart to matter. The Roma's 3.9 liter twin-turbo V8 produces about 612 horsepower through an eight-speed dual-clutch to the rear wheels, good for 0 to 60 in the mid 3 second range and a top speed near 199 mph. The 911 Turbo S makes about 640 horsepower from its 3.8 liter twin-turbo flat-six, sends it to all four wheels, and cuts 0 to 60 to the mid 2 second range with a top speed around 205 mph.

In practice the launch difference is larger than the horsepower gap suggests, because traction, not power, decides the first hundred feet. From a roll the two are much closer. The Ferrari's V8 also sounds and revs like an event, which is worth something that does not appear on a spec sheet.

If raw acceleration is the deciding factor, the decision is already made and it is the Porsche. Most buyers at this level are not choosing on that number alone.

This is where the two separate hardest. Porsche service is the least expensive in the supercar bracket by a clear margin, the dealer network is dense, and out-of-warranty repair costs are predictable. Tires, brakes, and consumables on a Turbo S are expensive by normal standards and cheap by exotic ones.

Ferrari running costs sit where you would expect. Scheduled service is priced at exotic levels, and specialist labor rates follow. The offsetting factor is Ferrari's included maintenance program, which covers scheduled service for a meaningful stretch of the car's early life. Verify exactly where a specific car stands in that program before you buy, because it changes the first several years of ownership cost significantly.

The single largest cost variable on either car is not the badge. It is the specific example. A car with complete authorized service history, no deferred maintenance, and honest paint costs a fraction of a neglected one to run, whichever one you choose. That is why we publish real prices and real history on our current inventory instead of asking buyers to call for a number.

Choose the Ferrari Roma if the car is going to be a weekend and evening machine, if design and sound are a meaningful part of what you are paying for, and if you want something that will not be parked next to three identical cars at dinner. It is the more emotional purchase and it is entirely rational to buy on that basis at this price.

Choose the Porsche 911 Turbo S if you want the performance to be available every day, in any weather, with the lowest ownership friction in the class. It is the car that gets driven, which is the strongest argument any performance car can make.

Buyers who want both usually end up in the Porsche first and a Ferrari second, and that order is worth thinking about. Whichever way you go, financing at this level is straightforward, and we arrange it in house through our exotic car financing program so the payment structure does not decide the car for you.
