Clarion Builds 1991 Acura NSX Review | Restored to greatness

Few automobiles garner as much mystique as the original Acura NSX. I worshiped this car from afar, consigned to the fact that the closest I was ever going to get to the steering wheel was a Playstation controller. When I got the email inviting me to drive Clarion Builds' restored and tuned 1991 NSX, I thought it was spam, a chain email with some generic header sent to a dozen or so people to garner some press coverage. Surely this wasn't a real invite where I get to drive a real NSX using my real hands and feet. Some people say don't meet your heroes. Some people are wrong. I knew the car by reputation. In roughly 10 months, Clarion Builds, a division of the Japanese electronics company mostly known for high-end audio systems, worked with partners like AEM and AutoWave to transform a '91 NSX with nearly a quarter-million miles on the clock into what you see here. Everything, from the engine to the bodywork to the leather on the seats, has been upgraded and restored with a mix of both OEM and aftermarket parts. The final product is a stunner. It's tuned, but not slammed, stanced or any other adjective that describes a car with compromised performance and questionable looks. It's simply a tastefully tuned NSX. The NSX, especially an early car with pop-up headlights, is one of the all-time great car designs. There are no unnecessary lines or curves. It's all purposeful. As expected with something with 230,000 miles, this NSX had a number of dings and dents. Clarion Builds has fixed those, replacing the hood and spoiler with carbon-fiber parts from an NSX-R. The fenders are slightly wider than stock, helping cover the staggered Rays Engineering VOLK ZE40 wheels, 18-inch up front and 19-inch out back. After seeing it in the flesh with the blue paint, black roof and bronze wheels, I don't think there is a better fit for this car. The original but tired 3.0-liter V6 and five-speed manual have been swapped for a 3.2-liter V6 and six-speed manual from a 2004 NSX. Stock, this engine is a wonderful ode to the internal combustion engine. It sings a sweet song all the way to a sky-high 8,200 rpm redline. Still, it wasn't enough. The engine now wears a Whipple-style supercharger, pushing roughly 9 psi of boost. Other modifications include a one-off carbon-fiber intake, a hand-built exhaust and a new ECU, all from AEM. All in, Clarion Builds says this NSX makes 403 horsepower and 296 pound-feet of torque at the wheels. God, it feels good to push this thing.

Pair of perfect Honda NSX Type Rs go up for auction in Tokyo

While the original Acura NSX is a brilliant supercar in any of its iterations, we never got the best version of it here in America: the Type R. Those came with Honda badges and are right-hand drive only. Unless you're in Japan or are lucky enough to come see an imported example elsewhere, you're not going to come across one of these. To see two practically perfect examples go up for auction at the same time is an even rarer sight. Some first-generation NSX Type R models (1992-1995 model years) can be imported to the U.S. now that they have surpassed the 25-year mark. However, this 1995 model is still a hair too new. Should that stop you from buying it and waiting a few months to take U.S. delivery? Certainly not. This car being offered at Tokyo's BH Auction with a grand total of 534 miles on its odometer. The seller claims it's 100% original and in pristine condition. Honda did a lot to transform the NSX into the first Type R of many to come. To start, engineers cut 308 pounds out of the car by using aluminum in even more places than before, deleting sound deadening, eliminating the A/C and stereo and using carbon-kevlar Recaro bucket seats. The 3.0-liter V6 was balanced and blueprinted. Then the suspension was given a full makeover with stiffer dampers, springs, bushings and a larger front sway bar. There were plenty of other little things throughout, but we'll spare you the long list. The number you need to know most is the estimated auction price. BH Auction thinks this NSX Type R will go for $227,000 - $272,000. 2005 Honda NSX-R View 21 Photos Next up is the ultra-rare 2005 Honda NSX-R. This R was based-off the NA2 NSX, so it has a 3.2-liter V6 and six-speed manual transmission with the new bodystyle that ditches the pop-up headlights. The 2005 model year was the last for the first-gen NSX, meaning this R is just about as new as they come. Many of the modifications that Honda did for the first Type R were repeated here. This model used carbon fiber more judiciously, though, replacing the hood, deck lid and spoiler with the lightweight material. The auction house claims just 140 NA2 NSX-Rs were made, so this is an incredibly rare car. Sadly, nobody here will be able to import it and drive it on American roads for quite some time yet. The price is estimated to come in at $345,000 - $436,000. That's pricey but this NSX has an even lower odometer reading than the other at just 348 miles.

Acura introduces a sleeker self-driving test car

As we creep ever closer to an autonomous-car future, one thing is for certain, most of the driverless cars we see being tested look hideous thanks to all the sensors strapped to the roof. Today Acura introduced its second generation Automated Acura RLX Development Vehicle with updated sensors and a more pleasing aesthetic. Gone is the spinning LIDAR system replaced with a more compact and robust version of the light detection and ranging technology. It's also got updated RADAR, camera, GPS and higher performance GPUs and CPUs as well as what Acura is calling "more intelligent software algorithms to support more complex testing scenarios." Acura and its parent company Honda have been testing autonomous cars at its GoMentum Station in the Bay Area since last year with a specially outfitted RLX (shown in the video above with the spinning LIDAR system). This new car will replace that vehicle. This article by Roberto Baldwin originally ran on Engadget, the definitive guide to this connected life.
