The P-51 Mustang is one of the most celebrated fighters of the 20th century. The WWII-era single-seat plane was introduced in the middle of the conflict and served to tremendous success in both the European and Pacific theaters. The most widely produced of the P-51 models was the D variant, which was put into service in 1944 and would become the workhorse (bad pun) of the USAAF in Europe. Outside of its beautiful shape, speed and maneuverability, what made the P-51D special was the Packard built V-1650 engine. The fighter’s power plant was a North American made supercharged version of the illustrious Rolls-Royce Merlin engine. This gave the P-51 an incredible top speed and a ceiling of over 41,000 feet. Perfect for long range bomber support. After the war, the iconic fighter even inspired Ford designers to name their new sports car after the P-51.
