Renault 5's Real-World Range Test in Mountainous Terrain

This article explores the real-world range and efficiency of the Renault 5 electric vehicle during a challenging road trip through the Carpathian Mountains, highlighting its performance across varied terrains and speeds.

Unlocking the Renault 5's Potential: Beyond City Limits

Endurance Test: A Romanian Mountain Expedition for the Renault 5

The Renault 5 embarked on a substantial 192-mile journey across Romania, traversing the demanding Carpathian Mountains and navigating stretches of motorway. This real-world test aimed to evaluate the electric car's capabilities beyond typical urban settings, pushing its limits in diverse driving conditions.

Remarkable Efficiency: Matching Official Ratings on Challenging Roads

During its mountain adventure, the Renault 5 achieved an impressive average energy consumption of 12.7 kWh/100 km, equating to approximately 4.9 miles per kWh. Based on its usable 52 kWh battery capacity, this translates to a theoretical range of 254 miles, almost perfectly aligning with the manufacturer's official WLTP rating. This indicates a high level of efficiency even under strenuous conditions.

Beyond the City: Proving Versatility for Longer Journeys

The successful completion of the 192-mile trip without needing a single charging stop underscores the Renault 5's practicality for extended travel. This performance challenges the perception of small EVs as solely city-bound vehicles, demonstrating their capacity to handle longer distances and varied terrains effectively. The journey included national roads with 56 mph speed limits and 18% highway driving at 80.7 mph, along with ascending the Transalpina, which reaches an elevation of 7,037 feet.

Ideal Conditions for Optimal Performance

The road trip benefited from mild weather, with temperatures ranging from 50°F to 77°F. These favorable conditions contributed to the car's strong performance, offering an encouraging benchmark for what owners can anticipate in similar driving scenarios. However, this test doesn't predict winter range or sustained high-speed motorway performance in harsher climates.

The Allure of the Renault 5: Style, Drive, and Practicality

The Renault 5 continues to impress with its appealing design, enjoyable driving dynamics, and robust electric vehicle specifications. Its ability to perform admirably on long, demanding trips, despite its modest battery size, reinforces its position as a compelling option in the EV market. The tested version featured a 148 hp motor paired with a 52 kWh battery, with future plans for a smaller 40 kWh battery and an LFP option providing up to 190 miles of WLTP range.

Rethinking EV Utility: Efficiency Over Excessive Battery Size

This real-world evaluation highlights a crucial point: a small electric vehicle isn't limited to being a secondary car reserved for short commutes. The Renault 5's achievement of completing a significant journey over mountains without recharging supports the argument for EVs that prioritize energy efficiency rather than merely offering ever-larger battery capacities. This demonstrates that even compact electric hatchbacks can meet a wider array of driving needs than commonly assumed.

NHTSA Demands Tesla Justify Cybercab's Legality Under Oath

The National Highway Traffic Safety Administration (NHTSA) has escalated its scrutiny of Tesla's Cybercab, issuing a formal Special Order demanding sworn testimony on how the autonomous vehicle complies with existing federal safety regulations. This directive comes after Tesla commenced commercial Cybercab operations in Austin, raising questions about the vehicle's unique design, which lacks traditional controls such as a steering wheel, pedals, and mirrors. The agency's action underscores a significant challenge to Tesla's self-certification approach, setting a deadline of September 30 for the automaker to provide a detailed and truthful response, under penalty of substantial fines.

On September 10, the NHTSA issued a Special Order, a legal demand that carries serious implications, including potential penalties of up to $139 million for non-compliance or falsification of information. This move follows an earlier Audit Query initiated shortly after Tesla's Cybercab service began in Austin on September 3. The Special Order, signed by NHTSA Chief Counsel Peter Simshauser, consists of 21 specific requests and is directed at Tesla's head of litigation and associate general counsel for regulatory affairs, emphasizing the gravity of the situation.

A core issue at hand is the self-certification process for vehicle designs in the United States. Automakers are typically responsible for certifying that their vehicles meet all applicable Federal Motor Vehicle Safety Standards (FMVSS), with NHTSA conducting checks post-certification. Tesla had certified the Cybercab as compliant with all relevant FMVSS. However, many of these standards were drafted with the assumption of a human driver. NHTSA's order explicitly challenges Tesla to defend its certification, particularly citing the provision that prohibits certification if there's reason to believe it's false or misleading. Tesla's potential defense centers on the argument that rules designed for human-operated vehicles are not applicable to fully autonomous robotaxis. Yet, NHTSA's stance is firm: current rules remain in effect until formally revised.

One of the most pointed inquiries in the Special Order, Request 19, addresses FMVSS No. 135, which mandates that service brakes be activated by a foot control. The Cybercab, by design, lacks any foot controls. NHTSA had previously stated that a vehicle without a foot-activated service brake could not meet this standard, and it is now demanding Tesla explain how it certified the Cybercab as compliant. Although NHTSA has proposed an amendment to FMVSS 135 for automated vehicles, this proposal is not yet law, and the agency is actively enforcing the existing foot-control requirement against Tesla.

Further requests probe Tesla's potential use of temporary manual controls during certification and the implications of their subsequent removal. The Safety Act prohibits certifying a vehicle with required safety equipment and then removing it before delivery. NHTSA is scrutinizing whether Tesla's Cybercabs, defined as vehicles without permanently attached conventional manual controls, violate this "make inoperative" prohibition. The order also questions compliance with various other FMVSS standards, such as those related to controls, telltales, shift-position displays, turn signals, mirrors, rearview images, and stability-control telltales, all of which typically assume the presence of a human driver and associated equipment.

Perhaps the most critical request concerns the absence of a Part 555 exemption. NHTSA's own 2022 rule indicated that significant FMVSS changes would likely be necessary for vehicles operated solely by automated driving systems to be manufactured for sale, unless the automaker obtained such an exemption. Tesla does not possess a Part 555 exemption, leading NHTSA to question the legal basis for selling the Cybercab. This contrasts sharply with Amazon's Zoox, which secured a temporary Part 555 exemption for its own purpose-built robotaxi, covering several federal standards including the foot-brake and mirror rules. Zoox followed a structured process of application, safety case presentation, and waiting for approval, receiving both a demonstration and a commercial exemption. Tesla, however, opted for self-certification and immediate commercial deployment, bypassing the exemption process altogether. The NHTSA's order highlights this divergence, implying a recognized legal pathway that Tesla chose not to follow.

This situation underscores a broader tension between rapid technological advancement and the pace of regulatory adaptation. While NHTSA has expressed openness to modernizing standards for autonomous vehicles, its current actions firmly assert that existing rules must be adhered to until formal changes are enacted. Tesla's approach, which some interpret as operating ahead of regulatory compliance, now faces a direct challenge from federal authorities, with significant legal and financial consequences at stake. The outcome of this order will likely set an important precedent for the future of autonomous vehicle development and deployment.
