2017 Elemental Rp1 2.3 Ecoboost (320 Hp)

The Elemental Rp1 2.3 EcoBoost, launched in 2017, represents a focused approach to the modern sports car. This lightweight, rear-wheel-drive roadster was designed and built by Elemental Motors, a British manufacturer, with a clear emphasis on driver engagement and performance. The Rp1 isn’t intended as a grand tourer, but rather as a highly capable track-day machine that is also street legal. It occupies a niche market, appealing to enthusiasts seeking a raw, unfiltered driving experience. The 2.3 EcoBoost variant, producing 320 horsepower, became the flagship offering, balancing substantial power with the car’s inherently low weight.

Technical Specifications

Powertrain & Engine Architecture

The heart of the Rp1 2.3 EcoBoost is, as the name suggests, Ford’s 2.3-liter EcoBoost inline-four cylinder engine. This engine, widely used in the Ford Focus RS and Mustang EcoBoost, is renowned for its responsiveness and tunability. The Rp1 utilizes a direct-injection system coupled with a single twin-scroll turbocharger and intercooler to deliver 320 horsepower. The engine is mounted longitudinally in the front of the chassis, driving the rear wheels. The six-speed automatic transmission, sourced from Ford, is calibrated for quick shifts and is a key component in maximizing the car’s performance potential. While a manual transmission was offered in some markets, the automatic became a popular choice for drivers prioritizing ease of use and consistent lap times.

Driving Characteristics

The Rp1 2.3 EcoBoost delivers a thrilling driving experience, largely due to its exceptionally low weight of 595 kg (1311.75 lbs). This translates to a power-to-weight ratio of approximately 537.8 horsepower per tonne, resulting in brisk acceleration and agile handling. The automatic transmission, while not offering the ultimate control of a manual, provides smooth and rapid gear changes, allowing the driver to maintain momentum. The gear ratios are tuned for performance, prioritizing acceleration over top-end speed. Compared to a hypothetical lower-powered version, the 320 hp EcoBoost provides a significantly more engaging experience, offering ample power for both road and track use. The car’s lightweight construction and well-balanced chassis contribute to neutral handling characteristics, making it predictable and confidence-inspiring in corners.

Equipment & Trim Levels

The Elemental Rp1 was not offered with traditional trim levels. Instead, it was largely sold as a highly customizable platform. Standard equipment included a basic digital instrument cluster, racing seats, and a minimalist interior focused on functionality. The interior materials were chosen for their lightweight properties rather than luxury. Optional extras included a more comprehensive data logging system, upgraded suspension components, and various aerodynamic enhancements. Customers could specify different wheel sizes (17-inch or 18-inch) and tire compounds to suit their intended use. Air conditioning and a stereo system were available as options, but many owners opted to forgo these features to further reduce weight.

Chassis & Braking

The Rp1 utilizes a lightweight spaceframe chassis constructed from high-strength steel. This provides a rigid and durable foundation for the car while minimizing weight. The suspension features double wishbones at the front and rear, with adjustable dampers and springs allowing for fine-tuning of the handling characteristics. Braking is provided by ventilated discs at all four corners, offering ample stopping power. The steering system is a rack and pinion setup, providing precise and responsive steering feel. The relatively low ride height (110 mm / 4.33 inches) contributes to the car’s stable handling and aerodynamic efficiency.

Market Reception & Comparison

The Elemental Rp1 2.3 EcoBoost received generally positive reviews from automotive journalists, who praised its exceptional handling, exhilarating performance, and raw driving experience. Critics noted that the car is not for the faint of heart, as it requires a skilled driver to fully exploit its potential. Compared to more conventional sports cars, the Rp1 offers a significantly more focused and visceral driving experience. Fuel economy, while not a primary concern for buyers of this type of vehicle, is reasonable given the engine’s output. Reliability has been generally good, although the car’s relatively low production volume and specialized components mean that parts availability can be a challenge. The automatic transmission was generally well-received, offering a balance of performance and convenience.

Legacy

The Elemental Rp1, while a niche product, has established a reputation as a highly capable and engaging sports car. Its focus on lightweight construction and driver involvement sets it apart from many modern sports cars that prioritize comfort and technology. The 2.3 EcoBoost powertrain has proven to be reliable and durable, and the car’s simple design should make it relatively easy to maintain in the long run. On the used car market, the Rp1 2.3 EcoBoost commands a premium price, reflecting its limited production run and unique driving experience. It remains a desirable option for enthusiasts seeking a pure and unfiltered sports car experience, and a testament to the benefits of a minimalist, performance-focused approach to automotive engineering.
