Navigating the Turbid Waters of Engine Innovation and Legal Action

The Troubled Genesis of Nissan's VC-Turbo Engine

Nissan's VC-Turbo variable-compression engine, a marvel of modern engineering, has regrettably become a source of considerable concern and legal contention. This innovative powerplant, designed to dynamically alter compression ratios for optimized performance and efficiency, has exhibited critical flaws, specifically bearing failures. These malfunctions can lead to severe and sudden engine damage, prompting a significant recall and, more recently, a prominent class-action lawsuit against the automaker.

Allegations of Foreknowledge and Warranty Denials Fueling Legal Battles

The recently initiated lawsuit, filed in Delaware by several VC-Turbo vehicle owners and lessees, asserts that Nissan possessed prior knowledge of these engine defects as far back as 2019. The plaintiffs contend that despite this awareness, the company continued to market and sell these potentially flawed vehicles. Furthermore, the legal filing accuses Nissan and its luxury arm, Infiniti, of unjustly refusing warranty claims for affected VC-Turbo engines, exacerbating the frustration and financial burden on consumers.

Vehicles Under Scrutiny and the Mechanics of Failure

The class-action suit specifically targets a range of Nissan and Infiniti models equipped with the KR15DDT and KR20DDET engines, including the 2021-2023 Nissan Rogue, 2019-2023 Nissan Altima, and 2019-2023 Infiniti QX50 vehicles. The core of the problem lies within the VC-Turbo's "multi-link" mechanism, which uses dual connecting rods per piston. Bearings within this intricate system, both for the adjustment mechanism and the crankshaft, are proving susceptible to premature failure, often resulting in engine collapse without prior warning.

Regulatory Investigations and Nissan's Response to Engine Defects

The National Highway Traffic Safety Administration (NHTSA) commenced an inquiry into reported VC-Turbo engine malfunctions in December 2023, preceding Nissan's broad recall in June 2025. This recall encompasses nearly 450,000 vehicles, including the 2019-2022 Infiniti QX50, 2022 Infiniti QX55, 2021-2024 Nissan Rogue, and 2019-2020 Nissan Altima. Despite Nissan's assertion to NHTSA that only a limited number of vehicles are potentially impacted and that subsequent engine improvements have been made, the class-action lawsuit extends its scope to all VC-Turbo engine variants, regardless of recall status, focusing on issues indicated by the presence of metal shavings in the oil.

Peugeot has unveiled the latest iteration of its 308 model, featuring a series of thoughtful enhancements that build upon its established strengths. This refresh underscores the vehicle's role as a compelling alternative in a market often saturated with SUVs, reinforcing its reputation for elegant design, a pleasurable driving experience, and competitive pricing. The update brings both subtle and striking alterations, including an illuminating emblem, a first for the marque, which is integrated into a more assertive front-end design. Despite these contemporary additions, the core appeal of the 308 remains steadfast, promising continuity in its well-regarded attributes. The comprehensive range of powertrain options, from electric to traditional internal combustion engines, ensures the 308 continues to cater to diverse driver preferences and environmental considerations.

The current generation of the Peugeot 308 has consistently impressed since its 2021 debut, establishing itself as a stylish, enjoyable, and accessible option for many drivers. This recent mid-cycle refresh aims to further solidify its position, introducing key design and technological upgrades without straying from its successful formula. The introduction of an illuminated badge, a prominent feature on its redesigned nose, marks a notable evolution in its aesthetic. This bold element is complemented by a revamped grille and distinctive 'three-claw' LED headlights, giving the 308 a more aggressive and modern visual presence. Inside, the cabin maintains its user-friendly 10-inch touchscreen and unique i-Cockpit layout, but enhances usability with more customizable shortcut toggles and premium ambient lighting options, elevating the overall interior experience.

Design Enhancements and Interior Refinements

The updated Peugeot 308 showcases a sophisticated evolution of its acclaimed design, particularly evident in its striking new front fascia. A standout feature is the illuminated Peugeot emblem, a pioneering design element for the brand, which commands attention on a heavily revised grille. This bold integration is flanked by innovative headlights featuring Peugeot's distinctive 'three-claw' LED signature, creating a visually powerful and recognizable identity. The overall effect is one of contemporary elegance, with strategic design choices that maintain the 308's attractive profile while incorporating cutting-edge automotive trends.

Inside the cabin, the 308 maintains its driver-centric focus and sophisticated layout, preserving the established 10-inch touchscreen and the distinctive i-Cockpit. However, the refresh introduces practical improvements, such as enhanced configurability for the five toggle switches positioned beneath the display, allowing for more personalized and rapid access to frequently used functions. High-end trim levels receive premium touches, including luxurious Alcantara upholstery and sophisticated aluminium accents, elevating the perceived quality and comfort of the interior. These refinements underscore Peugeot's commitment to delivering a modern, user-friendly, and upscale environment for both driver and passengers.

Diverse Powertrain Options and Efficiency Gains

The updated Peugeot 308 lineup boasts an impressive array of powertrain choices, reflecting a commitment to meeting diverse consumer needs and evolving environmental standards. The all-electric e-308, a cornerstone of the range, retains its 154bhp front-mounted motor but significantly enhances its practicality with an increased usable battery capacity of 55.4kWh. This upgrade translates to a notable improvement in range, now capable of achieving 280 miles on a single charge under the WLTP test cycle, extending its appeal for long-distance travel. Furthermore, the e-308 introduces innovative vehicle-to-load functionality, adding a new dimension of utility for external power requirements.

Beyond the electric variant, the 308 offers a robust selection of hybrid and traditional internal combustion engines. A plug-in hybrid option combines a 1.6-litre turbocharged four-cylinder engine with an electric motor and a seven-speed dual-clutch automatic transmission, delivering a combined output of 192bhp and an impressive electric-only range of up to 53 miles. For those seeking a non-plug-in hybrid solution, a 1.2-litre turbocharged three-cylinder variant paired with a six-speed dual-clutch automatic provides 143bhp and the capability for significant electric-only driving in urban settings. Notably, a diesel option, the 1.5-litre 128bhp turbodiesel BlueHDi with an eight-speed automatic, remains available, catering to drivers prioritizing fuel economy. The 308 continues to be offered in both five-door hatchback and SW estate body styles, ensuring that all powertrain options are accessible across different vehicle configurations.
