Comparison test: 2019 Acura RDX vs. compact luxury SUV competitors

Truth be told, if we were to compare the all-new 2019 Acura RDX with those compact luxury crossover SUVs it would most likely be cross-shopped against, you'd be looking at a different list. Even Acura admits that Lexus and Infiniti are the most likely bogies, but with the 2019 RDX, Honda's luxury brand is attempting to attract those customers who think as much with their hearts as with their heads. And for the most part, those folks have been buying from German brands: the Audi Q5, BMW X3 and Mercedes-Benz GLC-Class. So, to show how the new RDX compares to them, Acura actually provided examples of each during the recent press drive along with a Volvo XC60. All were determined to have greater emotional appeal than the last RDX, and we would certainly agree. For, as much as the previous-generation RDX made sense on paper, it was really hard to get excited about it. And when you're paying extra for a luxury vehicle, shouldn't you get a little excited? Well, as luck would have it, Consumer Editor Jeremy Korzeniewski and I were on hand in Whistler, British Columbia, for the press launch. We didn't have an abundance of time in each RDX competitor, but in conjunction with our usual comparison chart, our impressions should provide a good first taste of how the new RDX compares. Performance and fuel economy Contributing Editor James Riswick: On paper at least, the RDX is gutsier than its comparably powered European rivals. It also weighs the same or less, which logically should mean it'll be the quickest in a straight line. During my brief drives, though, I'm not sure it really stood taller than the three Germans. It at least matches them for smoothness, which is something that can't be said about the Volvo. Fuel economy is lower than them all when you consider all but the Mercedes come standard with all-wheel drive. It's also worth noting that all the competitors are available with engine upgrades, and unless Acura's forthcoming resurrection of Type S models includes the RDX, it should stay that way. Consumer Editor Jeremy Korzeniewski: Line 'em all up in a drag race, and I have a feeling the Acura would squirt away to victory. A good bit of that, though, would be due to its 10-speed automatic transmission, which offers a huge spread of ratios and fires off extremely quick shifts. In the real world, I'd guess fuel economy will be similar across the board, so I'm willing to call that category a draw.

Recharge Wrap-up: Honda FCV Concept comes to Detroit, Toyota seeks young green energy fellows

Honda will bring its FCV Concept to the 2015 North American International Auto Show in Detroit in January. The hydrogen-powered concept made its Japanese debut in November, and will now make its way to North America for the first time. The FCV concept improves upon the design of the FCX Clarity with a more striking appearance and roomier interior. Its smaller powertrain packaging means more space for people, and the FCV Concept seats five passengers. Honda also expects the next-generation fuel-cell car, which is scheduled to go on sale in Japan in March 2016, to cost less and have a range of over 300 miles. Read more in the press release below. The Mercedes-Benz B-Class Electric Drive has been awarded an environmental certificate from the TUV Sud technical inspection authority. The certificate is based not just on the vehicle's operation, but the entire lifecycle of the car, including production and recycling. The B-Class Electric Drive produces 24 percent less CO2 over its lifecycle than the Mercedes-Benz B180 when using the EU electricity mix, and 64 percent less when powered by hydroelectricity. Mercedes credits not just the use of electricity, but also the car's energy management system - such as its radar-based regenerative braking - for its carbon reductions.

One of its stops will have a wireless charging station where the bus will recharge for six to seven minutes before continuing on its route again. The charger is located under the road surface and the bus positions itself above it to charge inductively. About $1.3 million will come from the Swedish Energy Agency to fund the test project, which could save up to 90 percent of fuel costs. If expanded to a fleet of 2,000 buses, it could save up to 13 million gallons of fuel each year. Read more at Green Car Congress, and in the press release below. Sandia National Laboratories and Linde are teaming up to expand hydrogen fueling infrastructure. The two groups have signed an agreement to research and develop new hydrogen stations, as well as ways to make fuel cell vehicles more desirable for consumers. They are looking at ways to incorporate hydrogen into existing fuel stations where possible, and make sure that it is able to be done safely.

VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.
