Introduction

The 2021 Peugeot 308 SW III is a stylish and efficient station wagon that combines the practicality of a family car with the eco-friendly benefits of a plug-in hybrid. With its sleek design, advanced technology, and impressive fuel efficiency, this vehicle is an attractive option for those looking to reduce their carbon footprint without sacrificing performance or comfort.

Understanding Key Terms

Before diving into the specifics, let's clarify some essential terms:

  • Plug-in Hybrid Electric Vehicle (PHEV): A car that uses both a traditional internal combustion engine and an electric motor, which can be recharged by plugging into an external power source.
  • WLTP: Worldwide Harmonized Light Vehicles Test Procedure, a global standard for measuring fuel consumption and emissions.
  • CO2 Emissions: The amount of carbon dioxide released by the vehicle, measured in grams per kilometer (g/km).

Performance and Efficiency

The Peugeot 308 SW III is powered by a 1.6-liter engine paired with an electric motor, delivering a combined output of 225 horsepower. This setup allows the car to accelerate from 0 to 100 km/h (0 to 62 mph) in just 7.6 seconds, making it quite peppy for a station wagon.

One of the standout features of this model is its fuel efficiency. With a combined fuel consumption of just 1.2 liters per 100 kilometers (196.01 US mpg), it offers significant savings at the pump. The CO2 emissions are impressively low, ranging from 26 to 27 g/km, aligning with the Euro 6d emission standard.

The electric motor alone can propel the car up to 135 km/h (83.89 mph) and offers an all-electric range of 62-63 km (38.53 - 39.15 miles), making it ideal for short commutes or city driving.

Design and Features

The 308 SW III boasts a modern and aerodynamic design, with a drag coefficient of 0.277, contributing to its efficiency. Inside, it offers ample space with a minimum trunk capacity of 548 liters, expandable to 1574 liters with the rear seats folded down, making it perfect for family trips or transporting bulky items.

Technologically, the car is equipped with an 8-speed automatic transmission (e-EAT8) and features like electric power steering and ABS (Anti-lock Braking System) for enhanced driving comfort and safety.

Suitability for Different Lifestyles

The Peugeot 308 SW III is versatile, catering to various needs:

  • City Driving: Its compact turning circle of 10.7 meters (35.1 feet) and electric range make it ideal for urban environments.
  • Long-Distance Travel: With a maximum speed of 235 km/h (146.02 mph) and a comfortable ride, it's well-suited for highway journeys.
  • Family Use: The spacious interior and large trunk space accommodate family needs, from school runs to vacations.
  • Adventure Lifestyles: While not an off-roader, its towing capacity of 1450 kg (3196.7 lbs) with brakes allows for light adventure gear.

Strengths and Weaknesses

  • Strengths: Excellent fuel efficiency, low emissions, spacious interior, and modern design.
  • Weaknesses: Limited off-road capability, reliance on charging infrastructure for optimal use.

Conclusion

The 2021 Peugeot 308 SW III 1.6 Plug-in Hybrid is a well-rounded vehicle that offers a blend of performance, efficiency, and practicality. It's particularly well-suited for families and eco-conscious drivers who value space and low running costs. When considering your next car, think about what features matter most to you. Do you need extra cargo space or a vehicle that's easy to maneuver in the city?
