According to Car and Driver, it’s changing how it reports interior noise at a 70-mph cruise, adding sones alongside decibels to better reflect perceived loudness—because cabin sound is a real comfort variable, not a brochure line. Research on low-frequency road noise published in PLOS ONE found that this kind of interior noise can contribute to increased driver fatigue and reduced task performance. In 2026 weekend travel, the surprising trend is that many shoppers are prioritizing the car that arrives calm over the car that accelerates hardest. Horsepower still sells in ads. Quiet sells on hour three.
Quick takeaways
- Quiet wins weekends because it reduces fatigue, not just annoyance—research suggests low-frequency road noise can increase driver fatigue.
- Car and Driver’s move to add sones at 70 mph signals that “calm” is becoming a first-class metric, not a side note.
- Extra horsepower matters most for passing and towing; it matters less for a steady 70–80 mph cruise where the driver mostly hears wind and tires.
- The weekend “stress stack” is usually noise + micro-corrections + clutter, not 0–60 time.
- Best decision method: a simple 12-minute test (70-mph quiet + passing + a stop-cycle check) beats spec-sheet shopping.
What changed: quiet is being measured like performance
For years, performance was easy to market: horsepower, torque, 0–60, “sport mode.”
Quiet was harder. It’s subjective, and it depends on pavement, tires, and speed.
That’s why Car and Driver’s update is meaningful. The outlet notes it has long measured interior sound at a 70-mph cruise and is adding sones to better reflect perceived loudness. In plain terms: the industry conversation is shifting from “how fast” to “how calm,” because calm is what people feel after two hours.
This isn’t a luxury-only story either. As mainstream cars gained more power over the last decade, the marginal benefit of “even more power” for weekend driving has shrunk. Most weekend drivers already have enough passing ability. What they don’t have is a cabin that stays relaxing on rough asphalt and windy days.
Why it matters: fatigue is a road-trip problem, not a brochure problem
Horsepower is a single event: passing, merging, climbing a grade.
Noise is continuous. It’s always on.
A PLOS ONE study on low-frequency road noise reported that this interior sound environment can contribute to increased driver fatigue and reduced task performance. That’s not saying noise “causes crashes.” It’s saying noise can raise workload and tiredness—exactly what weekend trips are trying to avoid.
On a road trip, fatigue doesn’t arrive as one dramatic moment. It arrives as:
- turning the music louder to cover tire roar,
- feeling tense in crosswinds,
- reacting to constant little sounds and vibrations,
- arriving “done” even though the seat was fine.
In that context, a quiet cabin is a practical safety and comfort feature: it lowers the background load on the driver’s brain.
The anti-brochure truth: most weekend miles don’t use the horsepower you paid for
For weekend travelers, the most common pattern is:
- a steady 70–80 mph cruise,
- a few merges and passes,
- a stop cycle at the destination (parking, groceries, trailhead).
In that pattern, horsepower is used in short bursts. Quiet is used all the time.
That’s why the “more advanced” story can lose to the “easy to live with” story. A vehicle can be quick and still exhausting if:
- the wind noise ramps up at speed,
- the tires roar on coarse pavement,
- the cabin has constant alert chimes,
- or the driver has to keep making micro-corrections.
Quiet cabins reduce the urge to compensate. Less compensation often means less fatigue.
Quiet vs power: when each actually matters on a weekend
Quiet matters most when…
- the trip includes 2–5 hours of highway cruise,
- the route has coarse pavement,
- wind is common (plains, coastal highways),
- passengers want conversation without shouting.
Power matters most when…
- the car will tow,
- the route includes sustained steep grades at altitude,
- the vehicle is heavily loaded and frequently passes on two-lane roads.
The “trend” is really a re-weighting: people are deciding that the everyday weekend is mostly a comfort problem, not a power problem.
The hidden complicator: tech can make the cabin feel louder than it is
Even if the cabin is physically quiet, it can feel “noisy” if the car constantly nags:
- lane warnings,
- speed-limit alerts,
- driver monitoring prompts,
- parking sensors in stop-and-go areas.
This is another reason calm is winning. Weekend travel involves unfamiliar roads and more navigation changes. The vehicle that communicates clearly and quietly feels less tiring than the one that is technically advanced but constantly interrupting.
What this means in the U.S.
U.S. weekend travel often combines long highway legs with crowded destinations:
- busy parking lots,
- quick errands,
- unpredictable weather.
That mix rewards the vehicle that stays calm at speed and stays easy at stops:
- quiet enough to reduce fatigue,
- stable enough to reduce steering workload,
- practical enough to keep clutter out of the cabin.
When travel gets pricier and more crowded, drivers become less tolerant of “extra work.” Quiet cabins are a low-drama upgrade that helps every single weekend mile.
What you can do: the 12-minute “quiet beats horsepower” test
Use this before deciding between two vehicles where one advertises more power:
- 70-mph quiet test (5 min): audio off, fan low. Identify wind hiss vs tire roar.
- Passing test (2 min): a single 50–70 mph pass. Note if it feels strained.
- Lane-centering smoothness (2 min): does it hold center calmly or ping-pong?
- Stop-cycle test (3 min): park, open cargo, grab one bag. Does anything feel fussy?
If the quieter car passes the passing test, it’s usually the better weekend tool. The extra horsepower only wins if the quieter car can’t do the real-world pass or load comfortably.
Bottom line
Quiet cabins are becoming a bigger weekend-car trend than extra horsepower because quiet affects every mile, while power affects only a few moments. Car and Driver’s move to add sones to its 70-mph interior-noise reporting reflects how central “calm” has become. Research on low-frequency road noise supports why: the wrong sound environment can increase fatigue. For 2026 weekend travel, the winning car is often the one that arrives with the driver feeling fresh—even if the brochure says it’s the slower one.
