Modded budget Mazda Miata takes on new Porsche Boxster in more challenges

Earlier this month, our friends across the pond at Auto Express released the first in a two-video series that would see them try and build up a second-generation Mazda MX-5 Miata that could best a standard Porsche Boxster around the track. While that first video detailed the mods to the MX-5 - a supercharger, some suspension upgrades and a new set of super-sticky rubber being chief among them - and set baseline lap times for the stock car, today, we have the results of the 5,000-pound ($8,200) upgrade job.
Of course, we aren't going to spoil those for you. You'll need to watch the full video, which recaps the upgrades before digging into a comparison of both straight-line-speed differences between the 2.7-liter Porsche Boxster and blown Miata, as well as their behavior and lap times on the track.
Take a look and let us know what you think in Comments.

Why Mazda did so well and Volvo so poorly in Consumer Reports survey

The poor performances of Tesla and all three domestic automakers got the headlines in Consumer Reports magazine's latest reliability survey, but there were other results that caught our interest. Tiny Mazda notched the biggest gain among the 29 brands included in this year's list, leap-frogging nine spots to No. 3. Buick, which was in the top 10 last year, fell 11 spots to No. 19, the biggest decline of any brand. And then there's Volvo, a brand often vaunted for its quality and reliability, dropping six spots to dead last. What gives? For starters, all three brands benefited or suffered in large part due to their relatively small portfolio of vehicles. So when raves or complaints rolled in for even one particular model, as was often the case, it weighed heavily on the entire brand. That's especially true when it involves a relatively high-volume, hot-selling model such as the Buick Enclave (more on that in a moment). Mazda fared as well as it did despite the CX-3 losing Consumer Reports' influential "recommended" status due to problems with its climate system, including leaks from the condenser and refrigerant unit that triggered a service bulletin from the automaker in late 2016. Deputy auto editor Jon Linkov said that scratch didn't hurt the overall brand, since the CX-9 crossover and MX-5 Miata both jumped up to replace it on CR's list of newly recommended vehicles, thanks to several back fixes Mazda made to both models. For Buick, the redesigned Enclave SUV earned a "Much Worse Than Average" rating after owners reported problems with the new nine-speed automatic transmission it shares with the Chevrolet Traverse as well as some issues with the climate system. There were issues with rough shifting, plus complaints about the torque converter that necessitated fixes to the computer or outright replacement. "Again, similar stuff that we saw with the Traverse: both first-year vehicles, similar powertrains," LInkov said. He said all-new vehicles or redesigns typically fare poorly in CR's reliability survey due to issues that are hard to suss out before vehicles go into everyday use by consumers. The top-selling Encore and Envision fared well, Linkov said, but were outdone by the Enclave's problematic transmission components. The Enclave was Buick's second best-selling model through September at 35,227 units. Then there is Volvo, about which there is one word to sum up its woes: infotainment.

Mazda CX-5 updates bring nav to more trim levels

The refreshed 2016 Mazda CX-5 is already one of our favorite crossovers of its size for the model's engaging driving experience, upscale interior, and slick infotainment system. For a new 2016.5 model year upgrade that arrives in January, Mazda gives customers even more standard features to enjoy, but prices also tick upward. The Japanese automaker just gave the 2016 CX-5 light upgrades like LED signature lights and an update to the Mazda Connect infotainment system. The 2016.5 updates add a backup camera on every version except for the base front-wheel drive Sport with the six-speed manual. For buyers considering higher trims, all Touring and Grand Touring models get the welcome inclusion of standard navigation, and the Touring now comes with heated front seats, too. The extra tech comes with a jump in cost. As of Dec. 15 Mazda increases its delivery and destination charge from $820 to $900 for crossovers and $835 for cars. The change brings the base price of the front-wheel drive 2016.5 CX-5 with a manual gearbox to $22,695, and the top-spec all-wheel drive Grand Touring now retails for $30,770. 2016.5 Mazda CX-5 Adds More Standard Features to Best-Selling Compact Crossover - Backup Camera Now Standard on Most Trim Levels, Navigation Added to CX-5 Touring and Grand Touring - IRVINE, Calif., Dec. 18, 2015 /PRNewswire/ -- Just in time for Christmas, Mazda North American Operations (MNAO) has announced pricing and packaging for the 2016.5 Mazda CX-5 compact crossover, adding value and reducing complexity in CX-5's trim level structure. 2016.5 Mazda CX-5 Adds More Standard Features to Best-Selling Compact Crossover New for the mid-model year, a backup camera is now standard on all trim levels equipped with Mazda's SKYACTIV-Drive six-speed automatic transmission. CX-5 Touring models gain standard navigation and heated front seats. CX-5 Grand Touring models also add navigation as standard equipment.

"CX-5 buyers are educated, upwardly mobile, active-lifestyle individuals. With these updates, we aim to provide them with an even greater ownership experience." Previously, CX-5's backup camera was part of the Rear View Camera Package on the CX-5 Sport trim level. Navigation was available in the CX-5 Touring and Grand Touring Technology Packages.
