What the 2026 Mazda CX-70 MHEV Can Handle on a BC Summer Weekend — Towing, Trails, and the Sea-to-Sky

Summer in British Columbia is hard on a vehicle that is not built for it. The roads change quickly — from Burnaby's surface streets to gravel forest service tracks north of Squamish, from flat highway straightaways to the switchbacks above Alta Lake. The gear multiplies: bikes, boats, paddleboards, tent bags, coolers, wetsuits. The passengers have opinions about where to sit and how long the drive is. A two-row SUV that handles all of this without compromise is a specific thing, and the 2026 Mazda CX-70 MHEV was designed with exactly this kind of use in mind.

This article walks through four scenarios that describe a typical BC summer weekend — towing to the water, loading gear for a trail run, navigating gravel access roads, and the long drive home. Each one maps to something specific in the CX-70 MHEV's documented capability. None of it is abstract.

Towing on BC's Mountain Highways

The 2026 CX-70 MHEV tows up to 5,000 lbs when equipped with Mazda Genuine Towing Accessories and Mi-Drive's Towing mode is engaged. That figure covers most of what BC families actually tow in summer: a mid-size aluminum fishing boat on a single-axle trailer, a pair of jet skis on a tandem, a loaded utility trailer for a cabin weekend north of Pemberton.

The powertrain behind that rating is a 3.3 L turbocharged inline-6 engine with Mazda's M-Hybrid Boost system — a 48-volt mild hybrid that adds low-speed torque fill through an integrated starter-generator. On a loaded trailer, the most demanding moment is always the same: pulling from a dead stop on an uphill grade, which is unavoidable on the Sea-to-Sky Highway approaching Horseshoe Bay or climbing out of the Squamish valley. The M-Hybrid Boost's contribution at low RPM addresses that specific demand — the system adds torque at the moment the engine needs it most, before the turbo is fully spooling.

At the standard output setting, the inline-6 produces 280 hp and 332 lb-ft of torque on regular 87-octane fuel. Towing mode within Mi-Drive adjusts throttle mapping and transmission shift behaviour to optimize for the sustained, steady demand of a loaded trailer rather than the sporty response useful in other driving contexts. Standard Trailer Stability Control monitors sway and intervenes with selective braking if the trailer begins to oscillate — a relevant safety layer on the winding highway sections between Burnaby and Whistler.

For buyers stepping up to the GT trim, Trailer Hitch View uses the 360° camera system to display a live feed of the tow hitch area — useful when backing a boat trailer toward a ramp you cannot fully see in your mirrors.

Loading the Vehicle: Cargo and Gear Organization

The CX-70 MHEV's rear cargo area holds 1,131 L behind the second row — enough for a weekend's worth of camping gear, a pair of mountain bikes broken down into the boot, or a full kit of paddleboarding equipment without stacking items dangerously. With the second row folded, that figure expands to 2,147 L (measured with the moonroof), creating a flat, long load floor suited to awkward outdoor gear that needs to lie flat.

Remote-folding rear seats operate from a button inside the cargo area — the kind of detail that matters when your hands are full of equipment and you need to drop the row without going around to the side door. Mazda engineered the cargo area specifically with active use in mind: additional storage compartments, bag hooks to keep items from sliding, and a sub-trunk storage compartment beneath the cargo floor that stows valuables or small items out of sight when the vehicle is parked at a trailhead.

For a Burnaby family heading to Garibaldi Provincial Park or Joffre Lakes for a weekend, the practical result is a cargo area that can accommodate significant gear without forcing trade-offs between what gets loaded and who gets to ride.

Off-Road Mode and BC's Gravel Access Roads

Most of BC's best summer destinations sit at the end of a forest service road. The Callaghan Valley, the Elaho River corridor, the logging roads above Squamish that lead to alpine lakes — these routes are well-maintained in summer but still require a vehicle that can handle loose gravel, embedded rock, and occasional soft shoulders with confidence.

Mi-Drive's Off-Road mode adjusts the CX-70 MHEV's throttle response and AWD torque distribution for low-traction, unpaved surfaces. The effect is deliberate: throttle inputs become more progressive — less likely to break traction with a sharp jab on loose gravel — and the i-Activ AWD system's torque split shifts toward a more rear-biased, proactive distribution. This is not a rock-crawling mode for extreme terrain. It is calibrated for the kind of unpaved surface that British Columbia's outdoor destinations are actually accessed by — gravel roads that require awareness and a measured throttle rather than any specialized off-road hardware.

Kinematic Posture Control (KPC), standard on all CX-70 trims, continues to operate on gravel just as it does on pavement, suppressing body lift in corners to keep the vehicle settled when the surface is irregular. On the return leg from a forest service road back onto Highway 99 southbound — where the transition from gravel to pavement can feel abrupt — KPC's continuous background management keeps the chassis composed through the change.

The Drive Home: Highway Composure and Fuel Economy

The return drive from Whistler or Pemberton to Burnaby on a Sunday evening covers roughly 120–160 km on one of BC's most demanding highway corridors. Highway 99 includes long climbing grades, sweeping curves at sustained speed, and sections of roadway that require full attention regardless of how tired the driver is.

The CX-70 MHEV's KPC technology is specifically relevant here. By applying a small braking force to the inside rear wheel during cornering, KPC reduces the body roll and lift that accumulates on repeated sweeping bends. Passengers stay naturally upright, rear cargo stays settled, and the driver maintains a more connected sense of what the vehicle is doing through each corner — a meaningful difference over a long mountain descent.

The 3.3 L MHEV powertrain returns a combined fuel economy rating of 9.3 L/100 km at standard output. On a sustained highway cruise — which describes most of the Sea-to-Sky southbound — real-world consumption typically tracks close to the highway figure of 8.4 L/100 km. With a full tank, range on the highway is comfortably sufficient for a Burnaby-to-Whistler-and-back trip without a fuel stop in either direction.

The Automobile Journalists Association of Canada recognized Mazda's Large Platform MHEV powertrain — the same system in the CX-70 MHEV — with its Best Technical Innovation award at the 2025 AJAC Innovation Awards. The recognition specifically cited the powertrain's unconventional choice of a turbocharged inline-6 architecture over the downsized 4-cylinder engines more common in the segment, and noted its improvements to low-speed acceleration, gearchange smoothness, and fuel efficiency.
