Verdict
The BMW Z4 costs RM475,230 to the Mazda MX-5’s RM294,154, a RM181,076 stretch for 255 hp, 400 Nm and an eight-speed automatic against 181 hp, 205 Nm and a six-speed manual. It is also 372 kg heavier, yet delivers a claimed 5.4-second 0-100 km/h time and 250 km/h top speed. The MX-5 is the more compact car at 3,915 mm long and brings Smart City Brake Support front and rear, blind-spot monitoring and collision warning. For Malaysian buyers, the Z4 buys pace, a 280-litre boot and long-distance comfort features; the Mazda makes the stronger case for a lighter, manual roadster with more active safety kit and a five-year warranty.
Pick the BMW Z4 if you want 255 hp, 400 Nm, an eight-speed automatic and a 280-litre boot, and can justify the RM181,076 premium.
Pick the Mazda MX-5 if you want the 1,119 kg manual roadster, extra active safety aids and a five-year warranty for RM294,154.
