6. Lada Samara Turbo (1988-1993)
In the late 1980s, Lada sought a rally-capable hatchback to elevate its image, commissioning Porsche to reengineer the VAZ-2108 Samara. Porsche engineers replaced the stock engine with a 1.3 liter turbocharged DOHC four-cylinder, producing 145 hp at 6,500 rpm—a dramatic boost over the standard 67 hp. They reinforced the chassis, upgraded suspension, and recalibrated the K-Jetronic fuel-injection system.
The resulting Lada Samara Turbo could sprint to 100 km/h (0-62 mph) in approximately 8.9 seconds, showcasing surprisingly nimble handling. With around 5,000 built primarily for export markets, this Porsche-tuned Soviet hatchback remains a rare and intriguing piece of automotive history.
