Alvis was a pioneer of front-wheel drive vehicles. While J. Walter Christie had designed the first front-wheel drive racing car, which he drove in the 1906 Vanderbilt Cup, the next notable front-wheel drive race car was the supercharged &lt;a href="Alvis%2012/50"&gt;Alvis 12/50&lt;/a&gt; racing car designed by G. T. Smith-Clarke and W. M. Dunn, which was entered in the 1925 Kop Hill Climb in Princes Risborough in Buckinghamshire on 28 March 1925. Two months later (on Saturday, 30 May 1925), Harry Arminius Miller's Miller 122 front-wheel drive car was entered in the 1925 Indianapolis 500.
