Ford Mustang VI (facelift 2017) Shelby GT350 R 5.2 V8 (526 Hp): A Track-Focused American Icon

The Ford Mustang VI (facelift 2017) Shelby GT350 R 5.2 V8 (526 Hp) represents the pinnacle of naturally aspirated, track-focused performance within the iconic Mustang lineage. Introduced in 2017 as part of the refreshed sixth-generation Mustang, the GT350 R was an even more extreme variant of the already potent Shelby GT350. Designed from the ground up to dominate road courses, it stripped away non-essential luxuries and integrated advanced lightweight materials and aerodynamic enhancements. This limited-production model, built between 2017 and 2020, showcased Ford Performance’s engineering prowess, offering a visceral driving experience powered by a unique high-revving flat-plane crank V8 engine. It stood as a testament to American muscle car heritage, evolved for the demands of modern performance driving, cementing its place as a revered enthusiast machine in the global automotive landscape.

The Ford Mustang VI (facelift 2017) Shelby GT350 R: Engineering for the Apex

Building upon the strong foundation of the sixth-generation Mustang, which itself marked a significant leap forward in independent rear suspension and global appeal, the Shelby GT350 R was conceived with a singular purpose: track domination. The “R” designation indicated its no-compromise, race-ready nature. While the standard Mustang VI (facelift 2017) offered a range of engines from efficient EcoBoost to powerful GT V8s, the Shelby variants carved out a niche at the very top, with the GT350 R pushing the boundaries of what a factory-built Mustang could achieve on a circuit.

Engine & Performance: The “Voodoo” Heartbeat

At the core of the Ford Mustang VI (facelift 2017) Shelby GT350 R 5.2 V8 (526 Hp) lies one of Ford’s most celebrated modern engines: the 5.2-liter “Voodoo” V8. This naturally aspirated powerhouse is distinguished by its flat-plane crankshaft, a design more commonly found in exotic European sports cars than American muscle. This unique configuration allows for a higher redline and a distinct, aggressive exhaust note, setting it apart from traditional cross-plane V8s. With an impressive 526 horsepower delivered at a screaming 7500 rpm and 429.26 lb.-ft. of torque peaking at 4750 rpm, the Voodoo engine provides exhilarating, linear power delivery throughout the rev range.

The engine’s high-revving nature is complemented by a multi-port manifold injection system and a high compression ratio of 12:1, ensuring optimal fuel delivery and combustion efficiency. Power per liter stands at a remarkable 101.9 Hp/l, highlighting the engine’s advanced design for a naturally aspirated unit. Mated exclusively to a robust TREMEC 6-speed manual transmission, the Shelby GT350 R offers an unfiltered, engaging driving experience, placing the driver in direct control of its formidable power. The drivetrain architecture is classic American muscle: a front-longitudinal engine driving the rear wheels. With a curb weight of 3661.88 lbs, the car boasts an impressive weight-to-power ratio of 3.2 kg/Hp (or 316.7 Hp/tonne), underscoring its exceptional performance capabilities. Fuel economy, while secondary for such a vehicle, is rated at a combined 16 US mpg, reflecting its high-performance orientation.

Design & Features: Purposeful Aggression

The design of the Ford Mustang VI (facelift 2017) Shelby GT350 R 5.2 V8 (526 Hp) is a masterclass in functional aesthetics. Its Fastback body type is instantly recognizable as a Mustang, but every element of the GT350 R has been enhanced for aerodynamic efficiency and weight reduction. Externally, the car features aggressive front and rear fascias, a prominent rear spoiler, and a revised front splitter, all designed to generate significant downforce at high speeds, improving stability and grip on the track. The wider stance, courtesy of its extended track width (63.31 inches front, 63.7 inches rear), further contributes to its commanding presence and handling prowess.

One of the most distinguishing features of the GT350 R is its standard carbon fiber wheels, a significant weight-saving measure that reduces unsprung mass, thereby improving suspension response and handling precision. These 19-inch wheels (11J x 19 front; 11.5J x 19 rear) are shod with aggressive Michelin Pilot Sport Cup 2 tires, providing immense grip. The interior is equally focused: to save weight, the rear seats are removed, transforming the car into a strict two-seater. Air conditioning and a stereo system were also initially optional (though often added back), reinforcing its track-first philosophy. The braking system features large ventilated discs both front and rear, paired with Brembo calipers, providing exceptional stopping power and fade resistance crucial for repeated track use. The suspension setup, comprising an independent MacPherson strut with coil springs and an anti-roll bar at the front and an independent multi-link spring suspension with a stabilizer at the rear, is tuned for ultimate precision and minimal body roll. Assisting systems include ABS (Anti-lock braking system) for enhanced safety under hard braking.

Legacy & Market Impact: A Modern Muscle Car Legend

The Ford Mustang VI (facelift 2017) Shelby GT350 R 5.2 V8 (526 Hp) carved out an immediate and lasting legacy as one of the most capable track cars ever produced by an American manufacturer. It represented a bold move by Ford to challenge European sports car benchmarks on their own turf – the race track – while retaining the raw, visceral character expected of a Shelby Mustang. Its unique flat-plane crank “Voodoo” engine, with its exotic sound and high-revving nature, quickly became legendary among enthusiasts, offering an experience distinct from its cross-plane V8 counterparts.

In the fiercely competitive segment of high-performance pony cars, the GT350 R stood as a direct rival to the likes of the Chevrolet Camaro ZL1 1LE, another purpose-built track monster. While both offered immense performance, the GT350 R’s naturally aspirated, high-strung engine and lightweight philosophy offered a different flavor compared to the supercharged brute force of the Camaro. Its focus on driver engagement through the manual transmission, meticulous chassis tuning, and aerodynamic enhancements positioned it as a true driver’s car, appealing to those who prioritized precision and feedback over sheer straight-line speed.

Historically, the GT350 R also holds significant importance as potentially one of the last high-volume, naturally aspirated, track-focused V8 performance cars from Ford before the widespread adoption of forced induction in its top-tier Mustang models (like the subsequent Shelby GT500). This makes it particularly appealing to collectors and purists who cherish its analog driving feel and the unique character of its “Voodoo” engine. Its limited production run from 2017 to 2020, combined with its specialized engineering and exceptional performance, has ensured its status as a highly sought-after modern classic. The GT350 R not only upheld the storied Shelby name but also pushed the boundaries of what a Mustang could be, proving that American muscle could excel not just in horsepower, but in sophisticated, balanced track performance.
