2027 BMW 3 Series and i3 EV Spy Shots Reveal Subtle Design Differences

New spy shots from Germany show the next-generation BMW 3 Series and its electric i3 twin testing side-by-side, revealing subtle but distinct differences between the ICE and EV versions.

Why it matters: BMW is taking a unified design approach across different platforms, making it harder than ever to spot an EV in the wild.

The Details

• The Drive reports spy photographers captured both vehicles testing near the Nurburgring in Germany.
• BMW is using two different platforms: the Neue Klasse architecture for the electric i3 and an updated CLAR platform for the gas-powered 3 Series.
• Despite different underpinnings, both cars share a nearly identical front-end design and overall silhouette.
• The i3 EV features a taller rear roofline that remains more upright before tapering at a sharper angle than the ICE version.
• The charging port location on the i3 is positioned rearward, separate from where the gas cap sits on the 3 Series, likely to accommodate a future PHEV variant.

Key Differences

• Roofline: i3 EV is slightly taller with a more upright rear greenhouse
• Rear doors: Different window configurations due to modified roofline
• Rear window: i3 features a kinked rear window divider
• Charging port: Positioned rearward on i3, separate from ICE gas cap location
• Platform: i3 on 800-volt Neue Klasse; 3 Series on updated CLAR

Expected i3 Specs

• Architecture: 800-volt Neue Klasse platform
• Battery: Gen6 cells with 20% higher energy density
• Charging: 300-400 kW DC fast charging capability
• Range: Up to 500 miles (805 km) WLTP estimated
• Production: July 2026 (Munich), US models November 2026
• Price: Expected around $50,000 starting

EVXL’s Take

BMW’s strategy of making its EVs visually indistinguishable from ICE models reflects CEO Oliver Zipse’s technology-open approach that has served the automaker well as competitors backtrack on aggressive electrification targets. By downplaying visual differences, BMW lets buyers choose based on powertrain preference rather than making a style statement.

The real question is whether BMW can justify premium pricing once the i3 launches. With the federal EV tax credit expired and Tesla’s Model 3 starting around $37,000, that estimated $50,000 price tag creates a significant gap. The Neue Klasse platform’s 800-volt architecture and superior charging speeds are impressive, but BMW’s Q2 2025 EV sales dropped 21.2% in North America. Technology alone may not bridge the price gap with Chinese and American competitors.
