Mid-to-large cars, commonly classified as C-segment cars and often referred to as executive sedans, represent a segment positioned between mid-size cars (B-segment) and full-size luxury cars (D-segment) in passenger vehicle taxonomy. Offering generous cabin space, premium specifications, and robust performance, they primarily cater to corporate, executive, and affluent family needs.
The classification of mid-to-large cars is primarily determined by wheelbase and overall length. While definitions vary slightly across different industry sources, the widely accepted criteria are as follows:
Wheelbase: Typically ranges from 2.8 metres to 3.0 metres, with select long-wheelbase variants extending up to 3.3 metres.
Body length: Generally measures between 4.8 metres and 5.2 metres.
Engine displacement: Traditionally ranges between 2.4 litres and 3.5 litres.
It is worth noting that there is no globally unified mandatory standard for vehicle segmentation; car manufacturers frequently tailor dimensions to market and marketing strategies, which blurs these parameter boundaries.
Mid-to-large cars serve as a showcase for brand prestige and technical capability, while remaining the core battleground for legacy luxury marques. The segment is currently undergoing a profound transformation.
Rapid rise of new energy vehicles (NEVs): In Q1 2025, domestic sales in the mid-to-large sedan market surged by 53.3% year-on-year, driven by stellar NEV demand. On the mid-to-large sedan sales leaderboard, emerging EV contenders such as the Xiaomi SU7 have firmly established themselves among the top sellers.
Chinese domestic brands take the lead: In the mid-to-large SUV market, homegrown NEV models have secured the majority of positions in the top-ten sales rankings, thanks to precise product positioning tailored to diverse lifestyle scenarios.
ICE vehicle market share under pressure: While traditional luxury stalwarts such as the Mercedes-Benz E-Class and BMW 5 Series retain strong market appeal, they face intense pressure from NEVs, shifting the competitive landscape from "German-dominated" to "multi-player rivalry".
Key contenders in this segment are divided into two main camps:
Traditional ICE camp: The Mercedes-Benz E-Class, BMW 5 Series, and Audi A6L serve as the segment benchmarks. Historically, models such as the Toyota Crown and Hongqi H7 were also classic selections in this category.
New energy vehicle (NEV) camp: Domestic offerings such as the Xiaomi SU7, BYD Han, and NIO ET7 are rapidly building a strong market presence. Meanwhile, electrified models from legacy luxury marques, such as the BMW i5, have also entered the fray.
