Geiger has introduced the Ford Mustang GT 820, a comprehensively reworked version of Ford’s 5.0-litre V8 Mustang. With output raised to 820hp and a price tag of €109,450 (about $124,570), this German specialist’s latest creation targets buyers seeking supercar power in a familiar American muscle car shape.
Introduction to the Geiger Ford Mustang GT 820
Engine and Performance Upgrades
The headline figure comes from extensive engine modifications. Geiger fits a 2.9-litre supercharger, new crankshaft, forged pistons and steel connecting rods. The upgrades are paired with a cold air intake and a stainless steel sports exhaust. Torque climbs to 560lb ft (760Nm), a substantial gain over the standard Mustang GT. Compared to the stock car, the GT 820 adds 385hp and 160lb ft, more than doubling the original output. These changes make the GT 820 one of the most powerful Mustangs available from a European tuner.
Exterior and Chassis Enhancements
Geiger’s visual changes are as dramatic as the power increase. The GT 820 receives a carbon fibre body kit, including an open grille, front splitter, side skirts, rear diffuser and a prominent boot spoiler. Lightweight 20-inch forged alloy wheels are fitted with Michelin high-performance tyres, contributing to both style and road grip. Buyers can specify a bespoke paint finish for €5,900 extra, allowing further personalisation beyond the standard kit.
Chassis upgrades include a sports suspension system and the GT Performance package, which brings Brembo brakes, a limited-slip rear differential and a 3.73:1 final drive ratio. These changes aim to help the GT 820 deploy its power more effectively than a standard Mustang GT, providing improved handling and stopping power to match the increased output.
Power Comparison: GT 820 vs Standard Mustang GT
| Model | Power (hp) | Torque (lb ft) |
|---|---|---|
| Standard Mustang GT (2015) | 435 | 400 |
| Geiger Mustang GT 820 | 820 | 560 |
The GT 820 produces nearly double the power of a standard 2015 Ford Mustang GT. This significant increase highlights the extent of Geiger’s modifications and positions the GT 820 among the most potent Mustang variants available in Europe.
Pricing and Customisation Options
At €109,450, the GT 820 sits well above the price of a standard Mustang GT. The price reflects both the extensive mechanical work and the bespoke body kit. For those seeking further individuality, a custom paint option is available for an additional €5,900. Some of the upgraded components can also be ordered individually, allowing buyers to tailor the car to their tastes or budgets. However, the full package is aimed at those wanting an exclusive, high-performance Mustang that stands out both visually and mechanically.
Position in the High-Performance Mustang Market
The GT 820 joins a growing field of high-powered Mustang variants, including factory specials and other tuner models. Its combination of dramatic styling, extensive mechanical upgrades, and exclusivity makes it a notable entry for enthusiasts seeking something beyond the standard offerings. As interest in tuned American muscle cars continues in Europe, the Geiger GT 820 offers a compelling option for those prioritising both performance and individuality.
