BMW I3 94Ah REx 2016 Review: 195-Mile Range, Real Specs

The 2016 BMW i3 94Ah with Range Extender (REx) marks a pivotal advancement in electric vehicles, blending innovative battery technology with a compact petrol generator to address the common concern of limited range. This model upgrades the original i3’s 60Ah battery to a denser 94Ah unit, nearly doubling the electric-only capability while maintaining the car’s distinctive carbon-fiber chassis and rear-wheel-drive setup. Drivers benefit from up to 195 miles on battery power alone, extending to 288 miles when the range extender engages, making it a versatile choice for daily commutes and longer trips.

Powertrain Innovations and Range Capabilities

At the heart of the i3 94Ah REx lies a 33 kWh lithium-ion battery pack that fits seamlessly into the same space as its predecessor, adding only marginal weight. This upgrade delivers an official electric-only range of around 195 miles under optimal conditions, far surpassing the earlier model’s 100 miles. Real-world tests confirm this prowess, with reviewers achieving 194 miles on a full charge and tank, closely matching BMW’s claims.

The Range Extender feature introduces a two-cylinder 647cc petrol engine, not directly linked to the wheels but functioning as a generator to recharge the battery. With a 2.4-gallon (9-liter) tank, it extends total range without compromising the electric motor’s instant torque delivery. Acceleration from 0-62 mph takes 8.1 seconds, providing brisk performance that outpaces many rivals off the line, though it tapers at higher speeds.

• Electric-only range: Up to 195 miles (real-world ~194 miles)
• Total range with REx: 288 miles
• Charging time: 0-80% in 40 minutes via DC fast charging
• Fuel efficiency: Minimal petrol use, primarily for battery top-up

This setup ensures the vehicle always prioritizes electric propulsion, keeping operation whisper-quiet even when the generator activates in the background.

Driving Dynamics and Handling Excellence

True to BMW heritage, the i3 94Ah REx offers playful handling and rear-wheel drive, setting it apart from front-wheel-drive EV competitors. The low center of gravity from the floor-mounted battery enhances cornering agility, while the electric motor’s 184 lb-ft of torque delivers immediate response. On motorways, it cruises comfortably at 70 mph, with minimal wind noise thanks to aerodynamic design.

Testers note its sporty edge: quick steering, stable high-speed behavior, and surprising acceleration that can embarrass some performance cars from a standstill. Eco Pro and Eco Pro+ modes extend range further by adjusting throttle response and climate control, ideal for efficiency-focused drivers.

The REx’s added weight slightly impacts sprint times, but real-world driving remains engaging and confidence-inspiring.

Interior Comfort and Practicality

Step inside the i3’s futuristic cabin, crafted with sustainable materials like kenaf fiber door panels and recycled plastics. The minimalist dashboard features a 10.25-inch screen for navigation and iDrive controls, with optional head-up display for enhanced safety. Rear suicide doors provide easy access despite the carbon-fiber reinforced plastic (CFRP) body’s compact 157-inch length.

Upgrades in the 94Ah model include DC rapid charging capability, Apple CarPlay compatibility, and parking assist features. Cargo space measures 15.1 cubic feet, expanding with folded seats, sufficient for urban lifestyles. The 2+1 seating configuration prioritizes front passengers but accommodates occasional rear use.

Running Costs and Ownership Experience

Owning an i3 94Ah REx proves economical, with electric running costs pennies per mile. The pure EV variant excels here, but the REx adds flexibility without excessive fuel consumption—its tiny tank means infrequent refills. BMW’s app allows remote range monitoring, pre-conditioning, and charging scheduling.

High upfront costs are offset by low maintenance (no oil changes, regenerative braking reduces wear) and tax incentives. Resale values hold well for early adopters, especially with the battery warranty covering 8 years/100,000 miles.

Safety Features and Reliability

The i3 scores highly in crash tests, thanks to its rigid CFRP passenger cell and aluminum chassis. Standard equipment includes ABS, stability control, multiple airbags, and fatigue detection. Optional packs add forward collision warning and lane departure alerts.

Long-term reliability is strong for EVs, with fewer moving parts. The REx generator is durable but requires occasional servicing. BMW’s network supports CCS charging adapters for broader compatibility.

Environmental Impact and Market Position

As a zero-emission vehicle (ZEV) qualifier, the i3 promotes sustainable transport. Its lightweight construction (under 2,800 lbs) minimizes energy use, and the REx ensures practicality without full reliance on fossil fuels. Competitors like the VW e-Golf or Nissan Leaf lack the i3’s style and dynamics.

Pros and Cons Overview

Who Should Buy the BMW i3 94Ah REx?

Ideal for urban professionals needing a stylish, efficient car for 100+ mile daily drives with occasional longer journeys. It’s less suited for large families or heavy towing (max 150 lbs).
