Australia rewards a car that can cover serious distance. From weekend escapes out of Brisbane to long interstate runs and stretches of country highway where the horizon barely seems to move, these are the roads where a great luxury car earns its reputation.
The qualities that matter after several hours behind the wheel are very different from those that impress during a quick drive around town. Seat comfort, cabin refinement, ride quality and effortless performance become far more important, while good cruising range and driver-assistance technology can make hundreds of kilometres considerably easier.
Fortunately, the used prestige market is filled with executive sedans and grand tourers designed precisely for this kind of driving. The challenge is finding the used luxury cars that make a long Australian drive feel genuinely effortless.
What Makes a Luxury Car Good for Long-Distance Driving?
Comfort starts with the seats. A seat that feels supportive during a short test drive can become uncomfortable after several hours, so adjustability, cushioning and driving position all deserve careful attention.
Cabin refinement matters just as much. Wind and tyre noise that barely register around town can become tiring after hours at highway speed. The best luxury sedans isolate occupants from that noise while maintaining a settled, composed ride over the coarse road surfaces commonly found outside metropolitan areas.
Adaptive cruise control and lane assistance can also reduce workload on long motorway sections, although their availability varies between model years and individual specifications. Always confirm exactly what is fitted to the vehicle you are considering.
Then there are the basics: enough boot space for everyone's luggage, sensible cruising economy and enough range to avoid constantly planning the next fuel stop.
With those priorities in mind, several luxury cars stand out.
Mercedes-Benz E-Class and S-Class: Made for Effortless Cruising
The Mercedes-Benz E-Class has long been one of the benchmarks for executive long-distance travel.
Its combination of supportive seating, a quiet cabin and composed ride makes it particularly well suited to covering large distances. Six-cylinder and diesel variants add effortless performance and relaxed cruising characteristics that come into their own on the open road.
For buyers wanting another level of comfort, the S-Class takes the same philosophy significantly further.
Its focus on isolation, ride quality and passenger comfort makes it an exceptional interstate cruiser. Depreciation also means used examples can become considerably more accessible than their original new-car pricing suggests.
If comfort sits above outright sportiness on your priority list, both deserve serious consideration.
BMW 5 Series: Long-Distance Comfort with Driver Appeal
The G30-generation BMW 5 Series strikes an impressive balance between highway refinement and genuine driving enjoyment.
It settles comfortably into a long motorway journey, with a quiet cabin and excellent seating, but retains the steering and chassis character expected of a BMW when the road becomes more interesting.
The six-cylinder petrol and diesel variants are particularly well suited to touring, offering smooth power delivery and effortless overtaking performance.
Specification matters when shopping used. Buyers focused primarily on long-distance comfort may prefer examples with comfort-oriented wheel, tyre and suspension combinations rather than the most aggressive sporting setup.
For someone who wants the journey itself to remain enjoyable, the 5 Series is one of the strongest all-round choices.
Audi A6 and A7: Quiet, Stable and Understated
The Audi A6 takes a slightly different approach to the executive sedan formula.
Its appeal comes from understated styling, an exceptionally well-finished cabin and the stable, confidence-inspiring character that makes long highway stretches easy.
Many variants also feature Audi's quattro all-wheel-drive system, adding useful traction when Australian road trips encounter wet or unpredictable conditions.
The A7 Sportback brings many of the same strengths in a more distinctive grand-tourer shape, along with the additional versatility of its liftback design.
Both work particularly well for drivers who want a luxury car that feels calm and composed rather than overtly sporting.
Lexus ES and LS: Relaxed Luxury for the Open Road
For low-stress touring, Lexus makes a compelling case.
The Lexus ES prioritises comfort, refinement and efficiency. Its hybrid drivetrain suits buyers who want to reduce fuel consumption without giving up the quiet, relaxed character expected from a luxury sedan.
Its cabin is designed around comfort rather than sportiness, which becomes increasingly valuable as the kilometres accumulate.
The flagship Lexus LS takes that approach into full-size luxury territory. Its focus on passenger comfort, isolation and smooth performance makes it one of the most relaxing used luxury cars for serious distance driving.
For buyers less concerned with outright performance and more interested in arriving refreshed, both Lexus models deserve consideration.
Genesis G80: An Underrated Long-Distance Cruiser
The Genesis G80 has established itself as a credible alternative to the traditional European executive sedans.
A quiet cabin, comfortable ride and generous standard equipment make it particularly convincing on long journeys, where refinement matters more than badge recognition.
The spacious interior also works well when travelling with passengers, while used examples may retain remaining factory warranty depending on their age and original warranty terms.
For buyers willing to look beyond the established German marques, the G80 offers a compelling combination of comfort, equipment and road-trip ability.
Petrol, Diesel or Hybrid for Long-Distance Driving?
Choosing the right drivetrain can make almost as much difference as choosing the car itself.
Diesel remains well suited to drivers covering substantial highway distances. Strong low-rev torque makes overtaking and climbing effortless, while good highway economy can provide excellent range between fuel stops.
A six-cylinder petrol engine takes a different approach. Fuel consumption may be higher, but smoothness, quietness and effortless power delivery suit the character of a luxury grand tourer extremely well.
Hybrid models such as the Lexus ES prioritise efficiency and refinement. They can be particularly appealing to drivers whose road trips are mixed with significant suburban or urban use between longer journeys.
There is no universal answer. Consider the type of driving you actually do, how far you typically travel and whether your priority is range, performance, refinement or overall running costs.
What Should You Check When Buying a Used Luxury Touring Car?
High kilometres should not automatically rule out a potential long-distance car.
A vehicle that has accumulated kilometres predominantly through highway driving may have experienced an easier life than a lower-kilometre example subjected to years of short trips and stop-start traffic.
Service history is therefore more important than the odometer alone.
Check the condition and age of the tyres, inspect the suspension carefully and listen for unwanted cabin or suspension noises during the test drive. These components have a direct impact on the refinement that makes a prestige car enjoyable over long distances.
It is also worth confirming the exact driver-assistance equipment fitted. Adaptive cruise control, lane assistance, surround-view cameras and other features often varied between grades, model years and option packages.
Find a Luxury Car Built for the Long Drive
The best road-trip car is not necessarily the fastest or the most expensive. It is the one that still feels comfortable, quiet and effortless several hours after leaving home.
The Mercedes-Benz E-Class and S-Class excel at traditional luxury and comfort. The BMW 5 Series brings more driver involvement, while the Audi A6 and A7 combine stability with understated refinement. Lexus offers a particularly relaxed approach to long-distance travel, and the Genesis G80 provides a compelling alternative with generous equipment and impressive comfort.
