TrueDelta Reviews the Real Gas Mileage of the Cadillac CTS

Cadillac CTS Real Gas Mileage: Cons
Year	Comment
	With the 2011 528i, BMW pioneered the use of a turbocharged four-cylinder engine in a $60,000 midsize sedan on this side of the Atlantic. The point: fuel economy, specifically EPA ratings of 22 mpg city and 33 mpg highway even with all-wheel-drive (24/34 with RWD). Audi followed with an A6 2.0T good for 20/29 (25/33 with FWD) a year later. The new CTS takes the path blazed by the Germans, but much less effectively. Though the Cadillac weighs significantly less than the Audi or the BMW, its EPA ratings are lower, 19/28 (20/30 with RWD). The same is the case with the two 3.6-liter V6 engine options, even though unlike the turbo four they can be paired with an eight-speed (instead of a six-speed) automatic. The rear-drive-only Vsport barely evades the gas guzzler tax with ratings of 16/24. Even the 445-horsepower turbocharged 4.4-liter V8 in the BMW 550i does a bit better. In my real-world driving, the CTS's trip computer confirmed this shortcoming. Even considering that the outside temperature was near zero, post-warm-up averages that clustered around 18 were disappointing. Only by driving the car with a light foot could I nudge the suburban average over 20, and even then not much over. A 320-horsepower 3.0-liter 640i Grand Coupe tested a week earlier in similar conditions did at least one mpg better than the 272-horsepower, 2.0-liter Cadillac. And when I tested a 528i xDrive in slightly warmer temps it often managed 25 mpg (in an EcoPro Mode the Cadillac lacks). In one trip this BMW even touched 30. see full Cadillac CTS review

TrueDelta Reviews the Real Gas Mileage of the Honda Insight

Honda Insight Real Gas Mileage: Pros
Year	Comment
2020	Honda's initial approach to hybrid powertrain technology wasn't a winner. A weak electric motor (13 horsepower in the case of the 2010 Insight) sandwiched between a gas engine and a CVT wasn't able to deliver nearly as much of a performance or fuel economy bump as the much stronger electric motors in Toyota's radically different hybrid system. Starting with the 2014 Accord Hybrid, Honda tried a new approach. The new system relied entirely on a much more powerful (166 horsepower) electric motor to drive the wheels up to 43 mph, and only then directly engaged the gas engine via a single-speed transmission. This was the sort of elegant "we keep it simple" solution Honda used to be known for, and it worked far better. EPA ratings of 50 mpg city and 45 mpg highway were best-in-class, topping the Toyota Camry Hybrid. This system received further tweaks when the Accord was redesigned for 2018, with mixed results for mpg (now 48/47). The Toyota Camry, also redesigned for 2018, now scores 51/53 or 44/47 depending on trim level. When I learned that a new Honda Insight would utilize a similar hybrid system with a 1.5-liter engine instead of the Accord's 2.0-liter in a smaller, lighter car, I had high hopes. Could a 60-mpg rating happen? Well, it didn't. The Honda Insight LX and EX score 55 mpg city and 49 mpg highway in the EPA's testing. The tested Touring trim, with larger tires and a higher curb weight, scores a little lower, 51/45. Pretty good. But a Toyota Prius (58/53 or 54/50, depending on the variant), a Toyota Corolla Hybrid (53/52), or a Hyundai Ioniq (57/59 or 55/54) scores better. In my testing, the trip computer reported averages ranging from 45 mpg to 75 mpg in suburban driving. (Whether the system opts to charge or draw energy from the battery pack has a big effect on the reported average during short drives.) In one 20-mile drive around hilly Ann Arbor the trip computer reported an impressive 64 mpg--and 93.6 mpg during the initial three miles. But in a Toyota Prius I averaged 65 mpg over the entire week despite some colder weather--it struggled to top 60 when the air temperature fell to 40--and observed trip averages over 90 a couple of times. Air temperatures were usually in the 60s during the week I had the Insight, optimal for fuel economy. The Honda Insight disappointed in highway driving. When cruising near 80 mph, a speed at which it can't take much advantage of its hybrid configuration, the Insight averaged 40 mpg. Good, but little better than a non-hybrid Civic. I observed a bit over 60 mpg on the highway in the Prius. Given these results, I struggled with listing fuel economy among the reasons to buy the new Insight. On the one hand, all of its direct competitors have higher EPA ratings. On the other, the Insight's mpg compares very well to non-hybrids, and fuel economy will be a primary reason people buy one. see full Honda Insight review
