This review will be an unusual dual-trim review – I drove two separate Sequoias within a short time of one another. They’re not different enough to justify two separate reviews. Creature comfort isn’t the issue here – the Sequoia is roomy and quiet, save for muted engine roar from the 3.5-liter with one stone.
You know we are truly through the technological looking glass when an enthusiast driver can eschew the obvious choice of recommending the new yet traditional straight six-cylinder engined variant of the all-new BMW X3 range for the more affordable plug-in hybrid. The BMW X3 is a global success story, shifting more than 3.5
& It only stands to reason that the largest vehicles in a lineup, those vehicles for which fueleconomy has never been the sole focus, should be among the last to see battery power. Sadly, dipping into the throttle does send the fueleconomy reading south, as the 20 mpg combined estimate might be a bit optimistic.
As I’ve often said in these reviews, those of us who are self-described car enthusiasts sometimes forget that while we might place a premium on acceleration or ride and handling, most car buyers don’t. Oh, and with decent fueleconomy, if possible (27/34/29 here). The 2024 Subaru Crosstrek Premium fits that bill.
The appeal of the Forester will only grow having a hybrid option that offers more power and increased fueleconomy. liter Subaru boxer engine, which runs on 87 octane, is mated to a hybrid system with two electric motors, powered by a 1.1 Fueleconomy is rated at 35 mpg city and combined with 34 on the highway.
In Sport mode, the engine held on to revs, which lead to a bit of drone from the motor. Fueleconomy is listed at 21 mpg city, 27 mpg highway, and 23 mpg combined for both FWD and AWD vehicles. Flicking the D-mode switch into Sport mode stiffens things up a bit, but at the expense of some noise, vibration, and harshness.
Clean and Efficient Power & fueleconomy Available in two trimsSport and Sport Touringthe 2025 Civic Hybrid is powered by a 2.0-liter Fueleconomy numbers reported by Clean Fleet Report are non-scientific and represent the reviewers driving experience. The engine hums like a sewing machine.
The Kicks is redesigned, undergoing a radical makeover, more power, increasing in size and ground clearance, getting a new engine, and gaining all-wheel drive for the first time. Low-end grunt has been improved, but the engine still struggles at higher RPMs – a hill climb required me to go wide-open throttle and it was still an effort.
The gas engine just doesn't sound pleasant or smooth when you dig into the throttle. The CX-50's is likable due to its handling, and the hybrid powertrain gives a nice fuel-economy boost. It's just a shame that the gas engine can be so cacophonous when called upon. That's the good.
And it’s not just the hulking, squared-off, bulky yet brutally handsome exterior of the new Santa Fe, either, there’s a distinct sense that this large SUV – now also a HEV with no diesel or V6 engine options available so far – is trying to ape the premium off-roading brand in the interior as well. litres per 100km Engine 1.6-litre
