Core Viewpoint - McLaren, historically resistant to SUVs, is reportedly developing a hybrid five-seat SUV model, internally coded as "P47," expected to debut in 2028, indicating a shift in its long-standing position against SUVs [1][10][24]. Group 1: Historical Context - McLaren's previous stance against SUVs was rooted in its racing heritage and engineering principles focused on lightweight and performance [4][10]. - The brand's commitment to high-performance vehicles has been evident since its inception in 1963, with a focus on creating race-winning machines [4][5]. Group 2: Market Dynamics - The SUV market has proven lucrative, with brands like Lamborghini and Ferrari successfully integrating SUVs into their lineups, significantly boosting sales [13][15]. - McLaren's annual sales have stagnated around 5,000 units, far below competitors like Ferrari and Lamborghini, highlighting its struggle to absorb high R&D costs without a parent company for financial support [11][15]. Group 3: Strategic Shift - The impending entry into the SUV market is driven by external pressures, including stringent European emissions regulations and the need for a new revenue stream to support ongoing supercar development [11][15]. - The SUV is seen as an ideal platform for hybrid technology, allowing for larger batteries and higher price points to offset development costs [16][24]. Group 4: Product Development - The new SUV is expected to feature a hybrid system based on a V8 engine, targeting an output of 900-1000 horsepower, positioning it competitively against existing models like the Lamborghini Urus SE [22][24]. - Pricing for the new SUV is anticipated to be around 3 million yuan, aligning it with competitors while allowing McLaren to define its unique offering in the SUV segment [24][26].
