Motorweek 1993 Sports Car Test

Oh, the heady days of 1993, back when the Clinton Presidency was just getting underway, and it seemed like every hot new rock band was coming out of Seattle. Sports cars in the US had finally shaken off the shackles that slowed them during the ’70s and ’80s, and you could buy any number of legitimately quick vehicles again. MotorWeek recently went digging into its archives to find this six-model test from 1993 showing off some of the best semi-affordable performance coupes that money could buy at the time, and it’s priceless.

Featuring the 1994 model year Toyota Supra in twin-turbo guise and MY 1993 versions of the Porsche 968, Nissan 300ZX TT, Mazda RX-7, Dodge Stealth R/T Turbo and Chevrolet Corvette LT-1, MotorWeek definitely covered all of the bases. One thing that might surprise younger readers is these cars’ performance. The video only provides 0-60 acceleration times, but several of these vehicles would still be considered pretty potent today – over 20 years since going on sale. The Supra is especially impressive, hitting 60 miles per hour in just 5 seconds. Even today, that’s nothing to sneeze at.

Given their performance potential and still-attractive looks, it’s amazing that some of these coupes are old enough to drink now. The progress of interior design and safety equipment in the intervening years is pretty shocking, though. In most of these models, having two airbags is touted as a big deal. Scroll down to watch a Throwback Thursday blast from the past about some of the ’90s best sports cars.

Mazda rumored to use laser-ignition for next-gen rotary

Autocar is reporting that the next-generation rotary engine from Mazda may turn to a laser ignition system instead of traditional spark plugs. The report supposedly comes straight from the mouth of a shadowy senior engineer within the program. Mazda has been hard at work on the 16X Renesis rotary since around 2007 and the engine has seen quite a few evolutions over the intervening years. Autocar says that the design has seen displacement swell from 1.3 liters to 1.6 liters and that at least some parts of the engine have been designed to be made from aluminum to further reduce weight.

The work is in an effort to get the rotary to be more fuel efficient and provide more torque, the latter not usually being a chief attribute of this type of engine. According to Autocar, using a high-temperature laser ignition system would allow engineers to tune the Wankel to run leaner than systems that use a conventional spark plug. It would also reportedly allow the engine control module to more accurately adjust and monitor timing.
