Smart #5 Brabus Review: 645HP Electric SUV Redefines Performance

content:

Imagine merging supercar acceleration with family SUV practicality in an electric package. That's the Smart #5 Brabus – a limited-edition (1,000 units globally) powerhouse rewriting electric performance rules. After analyzing its Porto, Portugal test drive, I confirm this isn't just Smart's most powerful model; it's a technological showcase with 645 horsepower and a 800V architecture. Let's dissect why it challenges premium EV conventions.

Engineering and Performance

The 800V battery (100kWh capacity) delivers 475kW (645HP) and 710Nm torque, enabling 0-100km/h in 3.8 seconds. Unlike traditional EVs, Smart removed internal battery heaters, integrating a unified thermal management system. This innovation frees space, allowing faster DC charging: 10-80% in under 18 minutes at 400kW stations.

Range reaches 540km WLTP, but real-world mileage heavily depends on driving style – aggressive acceleration noticeably reduces distance. The dual-motor AWD system (standard on Brabus) activates clutch-based torque vectoring in 0.5 seconds during hard cornering. Remarkably, you’ll feel no drivetrain shudder when it engages.

Exterior and Interior Design

Brabus-specific cues include:

Red accents on grille, mirrors, and brake calipers
Unique 21-inch forged wheels
Rear roof spoiler and aggressive diffuser
"Brabus" embroidery on red seatbelts and steering wheel

The cabin features three screens: dual 13-inch displays (central and passenger) plus a 10.25-inch driver cluster. The augmented reality HUD projects navigation arrows and collision warnings directly onto the windshield – even working with sunglasses. A standout feature: swipe navigation maps between screens using three-finger gestures.

Technology and Practicality

Smart's navigation preconditions the battery when routing to chargers, ensuring optimal temperature for peak charging speed upon arrival. The 20-speaker BeatsAudio system (1,190W) supports Dolby Atmos, while ambient lighting offers 256 colors.

Practicality surprises:

630L trunk (expandable to 1,530L with folded seats)
500kg payload capacity
1,600kg towing rating
Front console cooler compartment
Rear seat "Camping Mode" converts seats into a flat bed

Driving Experience

Weight is significant (2,200-2,378kg), but the Brabus-tuned suspension masks it brilliantly. The steering feels direct, and body roll is minimal during spirited driving. Select "Brabus Mode" for maximum power and sportier exhaust synthesis (a digital sound enhancement).

Key observations:

Regenerative braking is strong but adjustable
Ride comfort remains composed even on 21-inch wheels
Noise isolation is exceptional below 120km/h
Off-road modes adjust traction control for sand/snow/rocks

Exclusive Analysis

The 800V architecture is more significant than raw horsepower figures. It enables faster charging, reduces cabling weight, and improves efficiency. While competitors like the Kia EV6 GT match its acceleration, few integrate this voltage class under $80,000.

One critique: Sport-themed graphics for the driver display in Brabus Mode would enhance the performance ethos. Nevertheless, this collaboration between Smart (backed by Mercedes-Benz engineering) and Brabus delivers unprecedented value in high-performance EVs.

Toolbox & Action Guide

Immediate Checklist for Buyers:

Verify local DC fast-charger compatibility (400kW+ recommended)
Test rear-seat "Camping Mode" functionality for your needs
Experiment with one-pedal driving settings in urban areas
Configure the AR HUD to display speed limits and navigation cues
Pre-condition battery via navigation when road-tripping
