1993 E1 Concept (Z15)
In 1993, BMW unveiled the second-generation E1 Concept, internally designated as the Z15, at the International Motor Show Germany in Frankfurt on September 9. This forward-thinking prototype succeeded the Z11 E1 Concept of 1991, which had been destroyed in a fire while charging. The Z15 was a bold step in BMW’s exploration of sustainable urban mobility, showcasing two variants: an all-electric model and a hybrid. Designed as a compact 3-door city car with seating for four, the Z15 retained the lightweight aluminum and plastic body of its predecessor, emphasizing efficiency and agility. The electric version, painted in striking green metallic with a matching green interior, was powered by a 19.2 kWh sodium nickel chloride battery, achieving a top speed of 80 mph (130 km/h) and offering an impressive range of up to 200 km in urban conditions.
The hybrid variant of the Z15, finished in vibrant red, integrated a 4-cylinder internal combustion engine sourced from the BMW K1100 motorcycle, paired with a 5-speed manual transmission, delivering 82 horsepower. This twin-powertrain approach highlighted BMW’s innovative spirit, testing the feasibility of combining electric and traditional propulsion for urban environments. The Z15’s design, influenced by Henrik Fisker during his tenure at BMW Technik, evolved from the Z11 with a sleeker, more futuristic aesthetic while maintaining compact dimensions (3.7 meters long) and a 2+2 seating configuration. Although the Z15 was technically advanced, BMW Technik concluded that battery technology required further development to make electric vehicles commercially viable, a challenge that persisted despite the concept’s promising performance.
Though the E1 Z15 never reached production, its legacy was profound, laying critical groundwork for BMW’s future electric vehicles, most notably the i3, launched 20 years later in 2013. The Z15’s pioneering use of sodium nickel chloride batteries, improved over the Z11’s sodium-sulfur setup, and its focus on lightweight construction and aerodynamic efficiency foreshadowed modern electric vehicle design principles. The project underscored BMW’s commitment to sustainable innovation, driven by external pressures like California’s zero-emission mandates, which also spurred competitors like General Motors’ EV1. The Z15 remains a testament to BMW’s early vision of eco-conscious urban mobility, blending driving pleasure with environmental responsibility, and its influence resonates in the brand’s electrified lineup today.
1993 E1 (Z15) Concept at a Glance: 4-seat electric and hybrid city car. The electric variant featured a rear-mounted permanent magnet synchronous motor with a 19.2 kWh sodium nickel chloride battery, delivering a top speed of 80 mph (130 km/h) and a range of up to 124 miles (200 km) in urban conditions. The hybrid variant used an 82 hp (61 kW) 4-cylinder engine from the BMW K1100 motorcycle with a 5-speed manual transmission. Rear-wheel drive, lightweight aluminum/plastic body weighed approximately 1,984 lbs (900 kg), with a length of 12.14 ft (3.7 m) and aerodynamic design. Unveiled at the 1993 Frankfurt Motor Show, held September 9-19.

Bloom: April at least, maybe earlier, definitely later.
Notes: iconic seedpod, wild that I only noticed this plant today and it already has seeds on it. The basal leaves remind me of geum/avens which we've been trying to look for.
