The runner-up deserves mention because if it had won, it would have been the second same model to do so. The eighth-generation 911 delivers performance and comfort in equal doses, with a generous helping of styling pizzazz.
Torque editor Jeremy Chua calls it "simply staggering", while logistics trainer Lionel Seah says it is a "precision driving machine that retains its claim to fame".
In many ways, it is even better than the very accomplished seventh-generation 911, which clinched the ST Car of the Year title in 2012.
But as it turned out, the competition is slightly tougher this year.
The second runner-up is also a sports car. The Alpine A110 has many fans among the judges. ST's breaking news editor Toh Yong Chuan says: "The Alpine is a breath of fresh air."
Medical doctor Kong Yongyao says: "If sports car greatness previously meant feeling like a precisely medium-rare steak, the Alpine is a perfectly fluffy, lighter-than-air, pandan chiffon cake."
Many compare the French two-seater with the Lotus Elise, but concur that the Alpine is more comfortable. Lawyer Sarjeet Singh notes: "It is like a luxury Lotus Elise, which means you can drive it every day."
Next on the totem pole is the stunning BMW 8-series, a grand tourer which Ms Tan says is a car which "drives as good as it looks".
Following closely behind is the Mazda 3, an everyday car which stands tall even among this year's rarefied contenders.
Lawyer Edric Pan says: "No other car at this price point has had as much thought put into it."
Mr Seah adds: "The Mazda 3 is bang for your buck."
