The 1934 Alvis Firefly was a relatively large British car, spanning a 118-inch wheelbase—just five inches shorter than the Speed 20. The 1496cc (91.3cid) ohv engine developed 50 brake horsepower at 4250rpm. Similar in design to the Speed 20 engine, albeit with two fewer cylinders, the Firefly’s four promised a top speed close to 70mph. The sporty Firefly’s low chassis height and rather wide track no doubt contributed to its reportedly excellent handling characteristics.
