Verdict
These two cost almost the same: the Stelvio is RM480,128 and the Z4 RM475,230, a RM4,898 gap. For a Malaysian buyer needing one car to cover people and luggage, the Alfa’s five seats, 525-litre boot and 64-litre tank make far more practical sense than the BMW’s two seats, 280 litres and 52 litres. The Z4 is the sharper paper-performance choice, reaching 100 km/h in 5.4 seconds against 5.7 seconds, with a 250 km/h top speed and a 6.5 L/100 km rating. But the Stelvio brings AWD, substantially more active safety kit and a five-year/150,000 km warranty.
Pick the Alfa Romeo Stelvio if you need five seats, a 525-litre boot, all-wheel drive and active safety systems including autonomous braking and lane-keeping assist.
Pick the BMW Z4 if a two-seat convertible, 5.4-second 0-100 km/h time, 250 km/h top speed and 6.5 L/100 km rated economy matter more than passenger and cargo capacity.
