Mercedes-Benz GLS: X166 Facelift vs X167 Facelift
Verdict
At RM888,888 against RM999,888, the outgoing Mercedes-Benz GLS X166 Facelift asks RM111,000 less and still gives you seven seats, all-wheel drive and a 333 hp/480 Nm petrol engine. The newer Mercedes-Benz GLS X167 Facelift is the quicker, larger car: 362 hp, 500 Nm, 0-100 km/h in 6.1 seconds and a 3,135 mm wheelbase. But the X166 counters with a quoted 680-litre boot and nine airbags. For a Malaysian buyer, this is not a walkover; it is newer performance and warranty versus luggage space and lower outlay.
Pick the Mercedes-Benz GLS X166 Facelift if you want the lower price, the larger quoted boot and nine airbags, and can live with the 6.6-second 0-100 km/h time.
Pick the Mercedes-Benz GLS X167 Facelift if you want the newer generation’s extra power, longer wheelbase, higher top speed and four-year warranty.
