They’re big, thirsty and difficult to manoeuvre around town, but the sports utility vehicle (SUV) remains as popular as ever. Buyers of these behemoths might not need their four-wheel-drive systems, but they definitely appreciate an SUV’s sheer size, a trait that makes them practical and gives them the ability to “part” traffic.
One of the most popular SUVs in Singapore is the Lexus RX350. Despite being the oldest in this contest, the RX350 continues to appeal to SUV fans (especially those who have no plans of going off-road) with its reputation for space and refinement.
Arguably the least famous contender in this contest is the Infiniti QX70 (previously known as the FX37, until Infiniti executed a rebadging exercise). Apart from its otherworldly styling, the QX70 also aims to make a statement in the segment with its array of standard amenities.
The newest SUV here is the Jeep Grand Cherokee Summit. Recently updated, this brash-looking American is equipped with plenty of off-roading technology and a newly improved drivetrain to improve running efficiency.
Which of these “suburban cowboys” would “lasso” concrete-jungle dwellers the most convincingly? Keep reading to discover the results of this SUV shootout.

The Lexus RX350 has all the traits a suburbanite would want in a suburban SUV. Designed as a “soft-roader”, the RX has the quietest cabin, creamiest ride and offers tons of space for passengers and their baggage. Its only real drawback is that it has fewer standard goodies compared to its rivals in this story. But when it comes to outright on-road comfort, the Lexus is still the undisputed king.
SUV buyers who put a premium on performance should definitely consider Infiniti’s QX70, for it is a total hoot to drive, striking an awesome balance between on-road power and off-road prowess. But the Infiniti is too finite in terms of practicality, which is important even to performance-loving SUV drivers.
Outshining its competitors in this contest is the Grand Cherokee Summit. Although it lacks the interior space of the RX350 and the scintillating pace of the QX70, the big Jeep boasts generous amenities, a commanding presence and serious off-roading credentials. In this story, it’s the “suburban cowboy” that would “lasso” concrete-jungle dwellers the most convincingly.
