2021 Hyundai Elantra vs. compact sedans | How they compare on paper

Despite the rising popularity of crossovers, the sedan market remains packed and fiercely competitive. It looks like it will stay that way with the introduction of the strikingly redesigned 2021 Hyundai Elantra. And since Hyundai was kind enough to provide plenty of specifications on the new car, we figured we ought to see how it stacks up to some of the latest and greatest small sedans on the market. For this comparison we picked the two best-sellers, the Honda Civic and Toyota Corolla, one of the other recently redesigned sedans, the Nissan Sentra, and a perennial enthusiast favorite, the Mazda3. Below you'll find a chart with all the raw numbers for your perusal. Following that will be our usual break down and analysis of the numbers and any other noteworthy features not included in the chart. Performance and Fuel Economy While the design and chassis are all-new on the Elantra, the base powertrain isn't. It uses a version of the naturally aspirated 2.0-liter four-cylinder shared throughout the Hyundai and Kia line-ups, and it's again paired with a CVT. With 147 horsepower and 132 pound-feet of torque, it's the second least powerful entry for conventionally-powered sedans, only ahead of the sluggish 1.8-liter base engine in the Toyota Corolla. For those looking for a peppy small sedan, the Mazda3's naturally aspirated 2.5-liter has the most power and torque, even ahead of the turbocharged Honda Civic's 174 ponies. On the other hand, the Elantra, which Hyundai says will have better fuel economy than the outgoing model, should get at least 36 mpg combined, and probably better, making it the most efficient non-hybrid of this group. For the best blend of power and efficiency, the Civic is likely the way to go, as its turbo engine can return 36 mpg combined in lower trims. If you want a manual transmission in this body shape, only the Civic and Corolla offer it. A manual transmission is available on the Mazda3 hatchback, and the turbo Civic can also be had with a manual in hatchback or Si forms. A new powertrain for the Elantra is the hybrid. It's unique compared to other hybrids in that it's coupled to a six-speed dual-clutch transmission, rather than an electronically controlled CVT (which is not the same thing as a CVT) or something too complicated to describe in this sentence (the Honda Insight).

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.

Nissan sells 3,117 Leaf EVs in May, climbs over 3,000 for first time ever

Chalk up a big win for the Nissan Leaf. In May, the world's most popular electric vehicle sold a record 3,117 units, the first time any pure electric vehicle has sold over 3,000 units in a month in the US (unless Tesla managed that feat but rolled the number into a quarterly report). This marks the 15th month in a row of record Leaf sales and the seventh where the Leaf was the top EV seller in the US. The challenge bar is set for someone to step up to compete with this all-electric wunderkind. Chevrolet did sell over 3,000 Volts once, in August 2013. The Leaf's one long-standing competitor, of a sort, is the Chevy Volt, which used to regularly outsell the Leaf but moved only 1,684 units in May. That's still an increase of 4.8 percent over 2013 but is part of a 4.5 percent decline in year-to-date Volt sales for 2014 compared to last year. The last time the Volt outsold the Leaf was October 2013. Chevrolet did sell over 3,000 Volts once, when it moved 3,351 in August 2013. Let's take another look at those 3,117 Leafs sold last month. They represent a 45.8 percent increase over May 2013, when 2,138 Leaf EVs were sold, so someone is doing something right in Japan and Tennessee. So far, Leaf sales in the US are up 36.4 percent year-to-date, to 10,389 EVs. That's just under half of the 2013 total, and it was accomplished in five months. In 2013, Nissan sold a total of 22,610 Leafs. Anyone want to hazard a guess where the total will be at the end of the year? As always, we'll have our detailed monthly sales write-up including other plug-in vehicles as well as hybrids and diesel car, up soon. For now, though, the big news is big Leaf sales. Read Nissan's press release below. Nissan Group reports May 2014 U.S. sales May 2014 May 2013 % Change Nissan Group Total sales (units) 135,934 114,457 +18.8 Nissan Division May sales 125,558 106,558 +17.8 Infiniti May sales* 10,376 7,899 +31.4 NASHVILLE, Tenn. – Nissan Group today announced total U.S. sales for May 2014 of 135,934 units, an increase of 18.8 percent over the prior year and a May record. Nissan highlights: Nissan Division set a May record at 125,558 sales in the month, an increase of 17.8 percent. This marks a monthly record for Nissan division in 14 of the last 15 months. May was the best-ever month for Nissan LEAF with 3,117 sales, an increase of 45.8 percent over the prior year. In May, LEAF passed 50,000 total U.S. sales since launch, further establishing it as the leader among electric vehicles.
