BMW Z4 M40i vs Toyota Supra
From the outside, the way in which the roadster concept has evolved is particularly plain to see from the car’s proportions. The new #BMW #Z4 has a low-slung, sporty, compact appearance when viewed from any angle. It is 85 millimetres longer than its predecessor (at 4,324 millimetres), 74 millimetres wider (now 1,864 millimetres) and 13 millimetres taller (1,304 millimetres). The shortening of the wheelbase by 26 millimetres to 2,470 millimetres serves to sharpen agility, as do the notably wider tracks – 1,609 millimetres at the front (+ 98 mm) and 1,616 millimetres at the rear (+ 57 mm). The car’s central seating position, low centre of gravity and minimised weight, as well as ideal 50 : 50 weight distribution, also contribute to the intoxicating dynamism of the new BMW Z4.
The roadster’s model line-up is spearheaded by a BMW M Performance version. The new BMW Z4 M40i conjures the power required for its breathtaking performance from a 3.0-litre six-cylinder in-line engine, whose inherently instantaneous response, hearty appetite for revs and smoothness combine with improved efficiency and reduced emissions. The new power unit’s standout features include a water-cooled exhaust manifold integrated into the cylinder head, sharper turbocharger response and superior acceleration, and direct injection technology which now works at increased maximum pressure of 350 bar. Drivers have a maximum output of 250 kW/340 hp at their disposal between 5,000 and 6,500 rpm, plus 500 Nm (369 lb-ft) of peak torque can be summoned from 1,600 to 4,500 rpm.
A ceaseless build-up of power enables the car to sprint from 0 to 100 km/h (62 mph) in 4.5 seconds. The new BMW Z4 #M40i posts combined fuel consumption of 7.4-7.1 litres per 100 kilometres (38.2-39.8 mpg imp), equating to CO2 emissions of 168-162 grams per kilometre. The straightsix engine now runs more cleanly, too, thanks to a system of emission control that comprises an enlarged, close-coupled catalytic converter and a gasoline particulate filter, and enables the new Z4 M40i to meet the extremely stringent Euro 6d-TEMP emissions standard.
The #Toyota #Supra design delivers a 50:50 weight balance while optimizing front-to-rear aerodynamic balance. Toyota sports car heritage is evident throughout. The double-bubble roof design, for example, recalls the Toyota 2000 GT and it reduces drag by shaving the roof center to reduce the projected frontal area without sacrificing occupant headroom.
The 2020 Supra will feature a 3.0-liter turbocharged inline six that will produce 335 hp and 365 lb-ft of torque. The torque comes on strong from very low engine speeds, thanks to a combination of a twin-scroll turbocharger, direct fuel injection and continuously variable timing on both the intake and exhaust camshafts. Engine response is further enhanced thanks to the inline six’s variable intake valve lift system that adjusts intake valve timing and duration.
The 8-speed automatic transmission delivers quick up- and downshifts and features paddle shifters for manual control when desired. Short ratios for the lower gears and a Launch Control function enable powerful acceleration with maximum traction. Toyota estimates 0-60 mph acceleration in 4.1 seconds. Top track speed will be electronically limited to 155 mph.
