Two of Ford's latest high-performance Mustangs will only be produced in limited numbers as the company recently announced that the 2015 Shelby GT350 will be capped at 100 units while the 2015 Shelby GT350R will only have 37 examples.

Originally unveiled back in November 2014, the 2015 Shelby GT350 is essentially a souped-up production version of the sixth-generation Mustang. Looking more aggressive than the standard version, the front gets an aluminum hood along with a splitter, redone aluminum fenders and a forward-angled grill.

The rear gets an additional diffuser and a lip spoiler while 19-inch alloy wheels wrapped in Michelin Pilot Super Sport can be seen on the side of the muscle car. The automaker reduced the amount of chrome trim fitted inside the GT350 in order to reduce sun glare while a flat-bottom steering wheel, improved gauges and Recaro seats remind drivers that this is a performance car.

Under the hood is a 5.2-liter naturally aspirated V8 that comes with Ford's first-ever application of a flat-plane crankshaft. It pumps out a healthy 507 PS with 542 Nm of torque and is mated to a 6-speed manual gearbox.

In addition, Ford also stated that half of the GT350s will come with the Technology Package while the other half will get the Track Package instead. It is set to go on sale on Q4 of the year.

The Shelby GT350R

The GT350R on the other hand debuted during the 2015 North American International Auto Show and was described by the company as the “most track-ready, road-going production Mustang ever built”.

Also labeled by the automaker to deliver “aerodynamic performance”, the GT350R features a bodykit that is comprised of a new ventilated hood, diffuser, ventilated wheel arches and side skirts. The rear has a large carbon fiber wing that aims to improve the GT350R's vehicle downforce and lift balance according to Ford.

The interior relatively carries over from the GT350 apart from the use of a bigger digital display on the center console.

The GT350R is also driven by the same 5.2-liter V8 found on the GT350 and also produces the same figures of 507 PS and 542 Nm.

The Shelby GT350R will be available later this year with no exact date yet from Ford.
